Sympy’s solve method doesn’t return all solutions on this relatively simple problem:

Problem Within SymPy, I am trying to create a set of X_i matrices each of size n_i x p where i = 1, … M (Pinheiro and Bates, 2000, pg. 58). Is this something that can be done? I’d also like to be able to print the set of matrices to see each one… Eventually, […]

I would expect sympy.powsimp to combine factors exp(subexprA)*exp(subexprB) into exp(subexprA+subexprB) in all cases. However, it fails to do so whenever either subexprA or subexprB are UnevaluatedExprs.

Suppose we have two functions f(a,b,c) and g(a,b,d) that we can express as expressions in Sympy.
How can we find the functions h(a,b), f'(x,c), g'(x,d) such that f'(h(a,b),c) = f(a,b,c) and g'(h(a,b),d)=g(a,b,d) via SymPy?

Look at the code below (the main testing code is in coeffsTest()):

I am using the Python library Sympy to calculate the partial fraction decomposition of the following rational function:

Given a series in variables x, y, z, I want to extract the kth term of this series using Sympy.

I am trying to produce the expression for the softmax of a vector in sympy. I am doing the following:
