- Remove Cython subpackage. The sources are not as cleanly
separated as the changelog implied.
-------------------------------------------------------------------
Mon Jul 27 09:26:20 UTC 2015 - toddrme2178@gmail.com
- Update to 0.16.0
* Highlights of this release include:
- A Cython API for BLAS/LAPACK in scipy.linalg
- A new benchmark suite. It's now straightforward to add new benchmarks,
and they're routinely included with performance enhancement PRs.
- Support for the second order sections (SOS) format in scipy.signal.
* New features
- Benchmark suite
+ The benchmark suite has switched to using Airspeed Velocity
for benchmarking.
- scipy.linalg improvements
+ A full set of Cython wrappers for BLAS and LAPACK has been added in
the modules scipy.linalg.cython_blas and scipy.linalg.cython_lapack.
In Cython, these wrappers can now be cimported from their
corresponding modules and used without linking directly against BLAS
or LAPACK.
+ The functions scipy.linalg.qr_delete, scipy.linalg.qr_insert and
scipy.linalg.qr_update for updating QR decompositions were added.
+ The function scipy.linalg.solve_circulant solves a linear system with
a circulant coefficient matrix.
+ The function scipy.linalg.invpascal computes the inverse of a Pascal matrix.
+ The function scipy.linalg.solve_toeplitz, a Levinson-Durbin Toeplitz solver,
was added.
+ Added wrapper for potentially useful LAPACK function *lasd4. It computes
the square root of the i-th updated eigenvalue of a positive symmetric rank-one
modification to a positive diagonal matrix. See its LAPACK documentation and
unit tests for it to get more info.
+ Added two extra wrappers for LAPACK least-square solvers. Namely, they are
*gelsd and *gelsy.
+ Wrappers for the LAPACK *lange functions, which calculate various matrix
norms, were added.
+ Wrappers for *gtsv and *ptsv, which solve A*X = B for tri-diagonal
matrix A, were added.
- scipy.signal improvements
+ Support for second order sections (SOS) as a format for IIR filters
was added. The new functions are:
* scipy.signal.sosfilt
* scipy.signal.sosfilt_zi,
* scipy.signal.sos2tf
* scipy.signal.sos2zpk
* scipy.signal.tf2sos
* scipy.signal.zpk2sos.
+ Additionally, the filter design functions iirdesign, iirfilter, butter,
cheby1, cheby2, ellip, and bessel can return the filter in the SOS
format.
+ The function scipy.signal.place_poles, which provides two methods to place
poles for linear systems, was added.
+ The option to use Gustafsson's method for choosing the initial conditions
of the forward and backward passes was added to scipy.signal.filtfilt.
+ New classes TransferFunction, StateSpace and ZerosPolesGain were
added. These classes are now returned when instantiating scipy.signal.lti.
Conversion between those classes can be done explicitly now.
+ An exponential (Poisson) window was added as scipy.signal.exponential, and a
Tukey window was added as scipy.signal.tukey.
+ The function for computing digital filter group delay was added as
scipy.signal.group_delay.
+ The functionality for spectral analysis and spectral density estimation has
been significantly improved: scipy.signal.welch became ~8x faster and the
functions scipy.signal.spectrogram, scipy.signal.coherence and
scipy.signal.csd (cross-spectral density) were added.
+ scipy.signal.lsim was rewritten - all known issues are fixed, so this
function can now be used instead of lsim2; lsim is orders of magnitude
faster than lsim2 in most cases.
- scipy.sparse improvements
+ The function scipy.sparse.norm, which computes sparse matrix norms, was
added.
+ The function scipy.sparse.random, which allows to draw random variates from
an arbitrary distribution, was added.
- scipy.spatial improvements
+ scipy.spatial.cKDTree has seen a major rewrite, which improved the
performance of the query method significantly, added support for parallel
queries, pickling, and options that affect the tree layout. See pull request
4374 for more details.
+ The function scipy.spatial.procrustes for Procrustes analysis (statistical
shape analysis) was added.
- scipy.stats improvements
+ The Wishart distribution and its inverse have been added, as
scipy.stats.wishart and scipy.stats.invwishart.
+ The Exponentially Modified Normal distribution has been
added as scipy.stats.exponnorm.
+ The Generalized Normal distribution has been added as scipy.stats.gennorm.
+ All distributions now contain a random_state property and allow specifying a
specific numpy.random.RandomState random number generator when generating
random variates.
+ Many statistical tests and other scipy.stats functions that have multiple
return values now return namedtuples. See pull request 4709 for details.
- scipy.optimize improvements
+ A new derivative-free method DF-SANE has been added to the nonlinear equation
system solving function scipy.optimize.root.
* Deprecated features
- scipy.stats.pdf_fromgamma is deprecated. This function was undocumented,
untested and rarely used. Statsmodels provides equivalent functionality
with statsmodels.distributions.ExpandedNormal.
- scipy.stats.fastsort is deprecated. This function is unnecessary,
numpy.argsort can be used instead.
- scipy.stats.signaltonoise and scipy.stats.mstats.signaltonoise are
deprecated. These functions did not belong in scipy.stats and are rarely
used. See issue #609 for details.
- scipy.stats.histogram2 is deprecated. This function is unnecessary,
numpy.histogram2d can be used instead.
* Backwards incompatible changes
- The deprecated global optimizer scipy.optimize.anneal was removed.
- The following deprecated modules have been removed. They had been deprecated
since Scipy 0.12.0, the functionality should be accessed as scipy.linalg.blas
and scipy.linalg.lapack.
+ scipy.lib.blas
+ scipy.lib.lapack
+ scipy.linalg.cblas
+ scipy.linalg.fblas
+ scipy.linalg.clapack
+ scipy.linalg.flapack.
- The deprecated function scipy.special.all_mat has been removed.
- These deprecated functions have been removed from scipy.stats:
+ scipy.stats.fprob
+ scipy.stats.ksprob
+ scipy.stats.zprob
+ scipy.stats.randwcdf
+ scipy.stats.randwppf
* Other changes
- The version numbering for development builds has been updated to comply with PEP 440.
- Building with python setup.py develop is now supported.
- Move Cython imports to another package

Sun Jan 25 01:43:07 UTC 2015 - arun@gmx.de
- specfile: update copyright year
- update to version 0.15.1:
* #4413: BUG: Tests too strict, f2py doesn't have to overwrite this array
* #4417: BLD: avoid using NPY_API_VERSION to check not using deprecated...
* #4418: Restore and deprecate scipy.linalg.calc_work
-------------------------------------------------------------------
Mon Jan 12 13:36:00 UTC 2015 - toddrme2178@gmail.com
- Update to 0.15.0
* New features
* scipy.optimize improvements
* scipy.optimize.linprog now provides a generic
linear programming similar to the way scipy.optimize.minimize
provides a generic interface to nonlinear programming optimizers.
Currently the only method supported is simplex which provides
a two-phase, dense-matrix-based simplex algorithm. Callbacks
functions are supported,allowing the user to monitor the progress
of the algorithm.
* The differential_evolution function is available from the scipy.optimize
module. Differential Evolution is an algorithm used for finding the global
minimum of multivariate functions. It is stochastic in nature (does not use
gradient methods), and can search large areas of candidate space, but often
requires larger numbers of function evaluations than conventional gradient
based techniques.
* scipy.signal improvements
* The function max_len_seq was added, which computes a Maximum
Length Sequence (MLS) signal.
* scipy.integrate improvements
* The interface between the scipy.integrate module and the QUADPACK library was
redesigned. It is now possible to use scipy.integrate to integrate
multivariate ctypes functions, thus avoiding callbacks to Python and providing
better performance, especially for complex integrand functions.
* scipy.sparse improvements
* scipy.sparse.linalg.svds now takes a LinearOperator as its main input.
* scipy.stats improvements
* Added a Dirichlet distribution as multivariate distribution.
* The new function `scipy.stats.median_test` computes Mood's median test.
* `scipy.stats.describe` returns a namedtuple rather than a tuple, allowing
users to access results by index or by name.
* Deprecated features
* The scipy.weave module is deprecated. It was the only module never ported
to Python 3.x, and is not recommended to be used for new code - use Cython
instead. In order to support existing code, scipy.weave has been packaged
separately: https://github.com/scipy/weave. It is a pure Python package, so
can easily be installed with pip install weave.
* scipy.special.bessel_diff_formula is deprecated. It is a private function,
and therefore will be removed from the public API in a following release.
* Backwards incompatible changes
* scipy.ndimage
* The functions scipy.ndimage.minimum_positions,
scipy.ndimage.maximum_positions and scipy.ndimage.extrema return
positions as ints instead of floats.
* Other changes
* scipy.integrate
* The OPTPACK and QUADPACK code has been changed to use the LAPACK matrix
solvers rather than the bundled LINPACK code. This means that there is no
longer any need for the bundled LINPACK routines, so they have been removed.

-------------------------------------------------------------------
Thu May 8 10:16:00 UTC 2014 - toddrme2178@gmail.com
- Update to version 0.14.0
* New features
* scipy.interpolate improvements
* A new wrapper function `scipy.interpolate.interpn` for
interpolation onregular grids has been added. `interpn`
supports linear and nearest-neighbor interpolation in
arbitrary dimensions and spline interpolation in two
dimensions.
* Faster implementations of piecewise polynomials in power
and Bernstein polynomial bases have been added as
`scipy.interpolate.PPoly` and `scipy.interpolate.BPoly`.
New users should use these in favor of
`scipy.interpolate.PiecewisePolynomial`.
* `scipy.interpolate.interp1d` now accepts non-monotonic
inputs and sorts them. If performance is critical, sorting
can be turned off by using the new ``assume_sorted``
keyword.
* Functionality for evaluation of bivariate spline
derivatives in ``scipy.interpolate`` has been added.
* The new class `scipy.interpolate.Akima1DInterpolator`
implements the piecewise cubic polynomial interpolation
scheme devised by H. Akima.
* Functionality for fast interpolation on regular, unevenly
spaced grids in arbitrary dimensions has been added as
`scipy.interpolate.RegularGridInterpolator` .
* ``scipy.linalg`` improvements
* The new function `scipy.linalg.dft` computes the matrix of
the discrete Fourier transform.
* A condition number estimation function for matrix
exponential, `scipy.linalg.expm_cond`, has been added.
* ``scipy.optimize`` improvements
* A set of benchmarks for optimize, which can be run with
``optimize.bench()``, has been added.
* `scipy.optimize.curve_fit` now has more controllable error
estimation via the ``absolute_sigma`` keyword.
* Support for passing custom minimization methods to
``optimize.minimize()`` and ``optimize.minimize_scalar()``
has been added, currently useful especially for combining
``optimize.basinhopping()`` with custom local optimizer
routines.
* ``scipy.stats`` improvements
* A new class `scipy.stats.multivariate_normal` with
functionality for multivariate normal random variables
has been added.
* A lot of work on the ``scipy.stats`` distribution framework
has been done. Moment calculations (skew and kurtosis
mainly) are fixed and verified, all examples are now
runnable, and many small accuracy and performance
improvements for individual distributions were merged.
* The new function `scipy.stats.anderson_ksamp` computes the
k-sample Anderson-Darling test for the null hypothesis that
k samples come from the same parent population.
* ``scipy.signal`` improvements
* ``scipy.signal.iirfilter`` and related functions to design
Butterworth, Chebyshev, elliptical and Bessel IIR filters
now all use pole-zero ("zpk") format internally instead of
using transformations to numerator/denominator format.
The accuracy of the produced filters, especially high-order
ones, is improved significantly as a result.
* The new function `scipy.signal.vectorstrength` computes the
vector strength, a measure of phase synchrony, of a set of
events.
* ``scipy.special`` improvements
* The functions `scipy.special.boxcox` and
`scipy.special.boxcox1p`, which compute the
Box-Cox transformation, have been added.
* ``scipy.sparse`` improvements
* Significant performance improvement in CSR, CSC, and DOK
indexing speed.
* When using Numpy >= 1.9 (to be released in MM 2014), sparse
matrices function correctly when given to arguments of
``np.dot``, ``np.multiply`` and other ufuncs.
With earlier Numpy and Scipy versions, the results of such
operations are undefined and usually unexpected.
* Sparse matrices are no longer limited to ``2^31`` nonzero
elements. They automatically switch to using 64-bit index
data type for matrices containing more elements. User code
written assuming the sparse matrices use int32 as the index
data type will continue to work, except for such large
matrices. Code dealing with larger matrices needs to accept
either int32 or int64 indices.
* Deprecated features
* ``anneal``
* The global minimization function `scipy.optimize.anneal` is
deprecated. All users should use the
`scipy.optimize.basinhopping` function instead.
* ``scipy.stats``
* ``randwcdf`` and ``randwppf`` functions are deprecated.
All users should use distribution-specific ``rvs`` methods
instead.
* Probability calculation aliases ``zprob``, ``fprob`` and
``ksprob`` are deprecated. Use instead the ``sf`` methods
of the corresponding distributions or the ``special``
functions directly.
* ``scipy.interpolate``
* ``PiecewisePolynomial`` class is deprecated.
* Backwards incompatible changes
* scipy.special.lpmn
* ``lpmn`` no longer accepts complex-valued arguments. A new
function ``clpmn`` with uniform complex analytic behavior
has been added, and it should be used instead.
* scipy.sparse.linalg
* Eigenvectors in the case of generalized eigenvalue problem
are normalized to unit vectors in 2-norm, rather than
following the LAPACK normalization convention.
* The deprecated UMFPACK wrapper in ``scipy.sparse.linalg``
has been removed due to license and install issues. If
available, ``scikits.umfpack`` is still used transparently
in the ``spsolve`` and ``factorized`` functions.
Otherwise, SuperLU is used instead in these functions.
* scipy.stats
* The deprecated functions ``glm``, ``oneway`` and
``cmedian`` have been removed from ``scipy.stats``.
* ``stats.scoreatpercentile`` now returns an array instead of
a list of percentiles.
* scipy.interpolate
* The API for computing derivatives of a monotone piecewise
interpolation has changed: if `p` is a
``PchipInterpolator`` object, `p.derivative(der)`
returns a callable object representing the derivative of
`p`. For in-place derivatives use the second argument of
the `__call__` method: `p(0.1, der=2)` evaluates the
second derivative of `p` at `x=0.1`.
* The method `p.derivatives` has been removed.
