umfpack: An error occurred: numeric factorization: not enough memory

Question

I'm having a problem while running a Scilab code. As title suggests, I get the error numeric factorization: not enough memory, related to the umfpack function.

In task manager I see a memory usage around 3GB (my system has 16GB). Can anyone help me with this issue?

Answer 1

My guess is that you are attempting to use umfpack with matrices which are too big, and then it is unable to allocate the memory required (probably more than the 13GB you still have available).
