Hello, I am using a TS to solve a differential algebraic equation (DAE). I do not provide the Jacobian matrix but instead set the TS to use a finite difference jacobian with coloring. For debugging, I only solve this DAE on one time step. Is there a way to output this finite difference jacobian in a matlab format (.m file)? I have already tried this flag : -mat_view ascii:ColFDJac.m:ascii_matlab , but when I use it the test takes too long. My guess is that this flag is trying to save all the matrices involved in the computations. I am only interested in the jacobian though. Thank you.
Best, Zakariae
