FIll Ratio in Maphys
How can I find the fill ratio in Maphys solver which is the number of nonzeros in the final matrix divided by the number of nonzeros in the original matrix. Can I say like this:
(IINFO(6), local matrix nnz(max) + IINFO(13), local schur nnz(max))/ (nonzeros in the original matrix).
What if the matrix is symmetric... should I multiply the numerator by two or what?
