Hi everyone, I have seen an ancient thread on this forum about automatic symbolic matrix differentiation, to have sympy compute expressions like:
∂(XY) = (∂X)Y + X(∂Y) d( A' ) = d ( A ) ' (transpose) etc... Are there still projects in this direction ? What has been decided about a symbolic matrix class (where one matrix = one letter ) ? I just implemented my own matrix differentiator method but it is something built kind of "beside" the rest of sympy (with its own printing and latex methods). However it could be easily added to the package: http://zulko.wordpress.com/2012/04/15/symbolic-matrix-differentiation-with-sympy/ Hope it helps until an 'official' solution comes to light :) Cheers, Valentin -- You received this message because you are subscribed to the Google Groups "sympy" group.
