does fraction_free_LDU only apply to square matrices?
I saw the original paper (http://ftp.cecm.sfu.ca/personal/pborwein/MITACS/papers/FFMatFacs08.pdf) it can apply to rectangle matrices. I've tried several dimensions for L,D,U, where A is rectangle, and got segfault always. Not sure why.

My matrix A is tall, 28 by 16. Haven't tried fat matrices yet.

By any chance, does symengine (and specifically the python wrapper) provide an equivalent of SymPy's linear_eq_to_matrix()? If not, any suggestions on the best way to accomplish the same thing?

@tgn3000, does it segfault in debug mode too?
@rbabich_gitlab, it doesn't exist, but you can copy the code from sympy (only a few lines). It should work. If it doesn't, let us know

I'll give it a shot. Thanks!
