Re: Octave: Sympy 0.7.6 installation steps.

[Constantine Frangos]

Hi Mike,

I followed the steps you suggested and managed to install
sympy 1.0 on my ubuntu 14.04 system, and then also installed 
the symbolic toolbox 2.4.0.

I ran the command octsympy_tests() and there were no unexpected 
failures, while for the symbolic toolbox 2.1.0 there were 89 
unexpected failures - see below.

Thanks again for your help.

Regards,
Constantine.


Symbolic toolbox 2.4.0:
Summary:

  PASS      1571
  FAIL         0
  XFAIL       24
  TIME      286s (233s CPU)


Symbolic toolbox 2.1.0:
Summary:

  PASS      1012
  FAIL        89
  XFAIL       28
  TIME      239s (196s CPU)

I would recommend using virtualenv to set up a Python environment with
SymPy 1.0. There are many resources for learning virtualenv, but briefly

  $ virtualenv ~/my-sympy-env  ## <- or choose whatever dir you like
  $ . ~/my-sympy-env/bin/activate
  $ pip install sympy
  $ octave
  ## do your Octave / octsympy work
  $ deactivate  ## or just exit the shell

The environment is self-contained and does not intrude on your normal
desktop or shell environment, so you'll have to activate it every time
you want to use this version of SymPy with Octave and octsympy.

And when you're ready to upgrade to Ubuntu 16.04, you can simply apt
install octave-symbolic and not deal with any of this.
