- Update to version 2.6.0
* New symbolic commands: ellipke, ellipticCE, ellipticCK,
ellipticCPi, ellipticE, ellipticF, ellipticK, ellipticPi,
harmonic, kroneckerDelta, pochhammer
* New `@double` numerical functions; these are wrappers around
SymPy, so they are slower than native floating-point
implementations: harmonic.
* Support for the new SymPy 1.1.1.
* `solve` now supports vectors of equations and vectors of
variables.
* Better warning for `sym(0.1)`, updated docs about floating
point.
* Double values can now be converted to their exact rational
value using `sym(0.1, 'f')`. Passing `'r'` gives the current
heuristic behaviour. Neither raises a warning.
* The default floating-point heuristics now check for square
roots of integers, so `sym(sqrt(2))` should work.
* `sym('i')` and `sym('I')` no longer create the imaginary unit:
use `sym(i)` or `sym(1i)`.
* `sym(e)` now gives the same as `exp(sym(1))`. However,
`sym('e')` and `syms e` continue to create a variable named
`e`.
* `sym` now accepts function handles such as anonymous functions
as inputs.
* `subs` is not approriate for numerical evaluation; add an
example in `help subs` which shows how to do this with
`function_handle`.
* Calling `sym(cell)` now creates a sym array instead of a cell
array. Old behaviour of creating a cell array was deprecated
in 2.5.0.
* Bug fix: isequal(n) for symfun's correctly tests the argnames.

Tue Jun 7 19:48:42 UTC 2016 - dmitry_r@opensuse.org
- Update to version 2.4.0
* New symbolic commands:
acsc, csch, gammaln, polylog, asec, dilog, hypergeom, psi,
asech, ei, hypot, resize, besseljn, expint, igamma, sech,
besselyn, ezsurf, jordan, signIm, cat, fresnelc, laguerreL,
sinint, cosint, fresnels, lgamma, sinhint, coshint, gammainc,
logint, ssinint
* Move some functions from the "specfun" package:
dirac, heaviside, laguerreL, lambertw
* Re-implement @double/laguerreL for numerical stability.
* Add spherical Bessel functions: these are called `besseljn` and
`besselyn`.

Tue Apr 28 20:53:43 UTC 2015 - dmitry_r@opensuse.org
- Update to version 2.2.1
* Fix an ascii pretty printing regression (issue #234).
* Other minor fixes for doctests, sympref and symreplace.
-------------------------------------------------------------------
Tue Apr 22 16:36:28 UTC 2015 - dmitry_r@opensuse.org
- Update to version 2.2.1
* New commands:
catalan eulergamma lambertw
* Installing symbolic package now check for Python and minimum
version of SymPy.
* Installations from Octave-Forge ("pkg install -forge symbolic")
should now work on Windows (thanks vassbu). You will need the
Python and SymPy dependencies. Or you can use the [bundled
package](https://github.com/cbm755/octsympy/releases)
* Added support for Python 3 (still works with Python 2 as well).
* Documentation improvements especially to assumptions. Examples
within documentation can now be tested with doctests, see the
`octsympy_doctests.m` function.
* Fix a warning on Octave 4.0.0-rc1 and make tests work properly.
* Other bug fixes: assumptions; symvar and symbolic matrix powers;
various display issues.
-------------------------------------------------------------------
Mon Mar 9 07:51:59 UTC 2015 - dmitry_r@opensuse.org
- Update to version 2.1.0
* New commands: columns, degree, formula, ismatrix, numden, rows
* Additional ways of calling symsum, symprod, and subs for better
compatibility with other symbolic toolboxes.
* Bug fixes in poly2sym, sym2poly, symfun, prod, horner, coeffs.
* Documentation improvements.
* Improvements to "argnames" and "formula" for the dependent
variables and dependent expression of a symfun.
* Improvements to assumptions.
* Improve symbolic sized matrices such as `A = sym('a', [n m])`.
* Drop python_cmd_string, which has been deprecated since v0.1.1.
