mem_usage consists of the following fields:

for_lu (float)
     The amount of space used in bytes for the L\U data structures.
total (float)
     The amount of space needed in bytes to perform factorization.
expansions (int)
     Number of memory expansions during the LU factorization.

Here is the caller graph for this function:
