An implementation of a symbolic toolbox using SymPy.
https://octave.sourceforge.io/symbolic
https://github.com/gnu-octave/symbolic
Feature parity with the other symbolic toolboxes.
The dependencies are Octave, Python, and SymPy. Consult the SymPy
website for details on how to install SymPy.
Start Octave.
At Octave prompt type pkg install -forge symbolic
.
At Octave prompt, type pkg load symbolic
.
At Octave prompt, type syms x
, then f = (sin(x/2))^3
,
diff(f, x)
, etc.
sudo apt install octave python3-sympy
.Get Octave for Windows.
At the Octave prompt, type pkg install -forge symbolic
.
At the Octave prompt, type pkg load symbolic
.
At the Octave prompt, type syms x
, then f = (sin(x/2))^3
,
diff(f, x)
, etc.
If you encounter any difficulties (even minor ones) please read and
if possible help us improve the
wiki page on Windows Installation.
Although this package is designed for GNU Octave, it will work with
Matlab. Currently only the slower system()-based communication is
available.
Download the latest release, e.g., octsympy-matlab-2.7.0.tar.gz
.
Unzip it somewhere and add it to your Matlab Path.
The .m files for Matlab have been reformatted for Matlab comment
conventions, but are otherwise the same as the Octave source.
We have a list of things to work on tagged help
wanted.
Some of these should be quite easy to fix and would be a great way to
get involved. Come join us!
How to hack on the code:
Clone the repo with git (preferred, but you can use the "Download
ZIP" instead if you want).
Run Octave in the inst/
directory. It should be safe
to do this even if you have the released version of the package
installed (but not loaded).
Python code is generated to do the actual work. Each sym object keeps
a text field for display purposes and a string (a SymPy srepr
). The
objects are communicated between Python and Octave by passing the
srepr string back-and-forth. Currently pure m-file (and Python)
implementation, no code to be compiled.
There was a previous "symbolic" package in Octave Forge based on
GiNaC. Its history has now been merged into this project.
