What it says on the tin!

Many thanks to the author of https://zulko.wordpress.com/2012/04/15/symbolic-matrix-differentiation-with-sympy/ for laying out a much earlier version of this I have built on.

setup:

sudo apt-get install python3-sympy

(you can also use python2, but tab completion is nice)

##Example usage:

from symbdiff import diff a=diff.MatrixSymbol('a',5,1) print(diff.matDiff(diff.Transpose(a)*a,a)) [a'd(a) + d(a)'(a)]

X=diff.MatrixSymbol('X',5,5) print(diff.matDiff(diff.Transpose(a)Xa/(a*diff.Transpose(a)),a))

[d(a)(Xa') + aXd(a)' + a0(a')]
