I would like to express formulas that involve both traditional
matrix-matrix multiplication and elementwise multiplication. To be clear,
these are the operations that correspond to "*" and ".*" in MATLAB,
respectively. I don't want to actually instantiate matrices, as I'm not
interested in their components (the final result I'm looking for is to
generate Python or MATLAB code that also won't ever index into the
matrices). For instance, if A, B, C are three square matrices of size n x
n, I would like to be able to express what is meant by the MATLAB code
A*(B.*C)
which should mean
\sum_j A_{ij} ( \sum_{p,q} B_{pq} * C_{pq} )_{jk}
Is there any way to do this in Sympy?
