I am using spilu (incomplete LU decomposition for sparse matrix) in scipy: https://docs.scipy.org/doc/scipy-0.14.0/reference/generated/scipy.sparse.linalg.spilu.htmlHowever there is an option call fill_factor which is quite unclear to me.If fill_factor=100, does it mean the matrix is full; and fill_factor=50 means the matrix is half-full?
How to use fill_factor in spilu (scipy)
