Update: octave-symbolic 2.0.0

Description

octave-symbolic has been updated to version 2.0.0.

octsympy 2.0.0 (2015-02-04)
===========================

 *  Octsympy is now the "symbolic" package for Octave Forge.  There
    was a previous "symbolic" package (based on GiNaC) which reached
    version 1.1.0.  To prevent confusion, we are now at version 2.0.0.
    Additionally, the history of the two projects has been merged
    (thanks Carnë Draug).

 *  New commands:

          coeffs
          ipermute
          isallconstant
          isconstant
          nchoosek
          permute

 *  Fixes for developement version of SymPy.

 *  Fixes for vpa and vpasolve: high precision should be more reliable.

 *  Improve handling `sym(pi/3)` and other small fractions of pi.  It
    works but you'll still get a warning and 2*sym(pi)/3 is really the
    preferred approach!  `sym(-pi)` now works.

 *  No longer needs to autogenerate a bunch of functions at install
    time: hopefully making it easier than ever to get involved!

octsympy 2.1.0 (2015-03-06)
===========================

  * 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 (thanks @rocketsound),
    prod, horner, coeffs.

  * Documentation improvements.

  * Improvements to "argnames" and "formula" for the dependent
    variables and dependent expression of a symfun.  These are now
    implemented for basic sym objects as well.

  * Improvements to assumptions.  E.g., `x = assume(x, 'positive')` no
    longer mucks around in the workspace for other instances of x (it
    still does this with no output argument, for compatibility with
    other symbolic toolboxes).  You can use multiple assumptions with
    sym and syms, e.g., `syms n m positive even`.

  * Improve symbolic sized matrices such as `A = sym('a', [n m])`.
    These are still experimental; they correspond to MatixSymbols in
    SymPy and may need a recent SymPy development version.  For now,
    the `size(A)` returns "1x1" although internally `NaN` is used for
    symbolic-sized dimensions.  Enabling `size(A)` to return "NaNx3"
    may occur later.

  * Drop python_cmd_string, which has been deprecated since v0.1.1.
