Input Parameters
mat | - the matrix
|
row | - row permutation
|
col | - column permutation
|
f | - expected fill as ratio of original fill.
|
level | - number of levels of fill.

Probably really in-place only when level of fill is zero, otherwise
allocatesnew space to store factored matrix and deletes previous memory.
