For some time I have wanted to start using Gnu Octave. The last
time I looked, the authors of that code considered any differences
between MatLab and Octave to be a bug in Octave. It appears that
Octave now has a wide variety of packages which support various
computational methods, similar to MatLab's Toolboxes. I did not
see an Octave package for PDEs, though.
At one time the MathWorks would sell one a copy of MatLab,
Simulink and whatever toolboxes one wished to purchase for a
fraction of the commercial cost if one signed an agreement that
precluded the commercial use of that copy of MatLab. I did this in
2000; when I went to re-up, The MathWorks informed me that they no
longer supported that option. Later on, I believe they expanded
the capabilities of the student version of MatLab. I briefly
pursued the use of that but did not explore it in depth.
MATLAB is very economical for home use
Although good for numerical work, I believe Mathematica is king when it comes to symbolic maths. There's a home version of that, but it is more than twice the price of MATLAB.
However, if you have a lot of patience, then you can use Mathematica for free on a Raspberry Pi. I tried it on an earlier Pi (not sure what version), but not a very early version of the Pi. I found Mathematica to be painfully slow.
