[SciPy-user] problem using umfpack.lu()
Sat Dec 20 12:03:02 CST 2008
I'm trying to solve the problem of compute the determinant of a sparse
matrix, as I've written in the previous mail.
I find that the LU decomposition can be useful for this task but when I
use umfpack.lu(A) for A complex sparse matrix, this error appears:
"matrix must have float64 values"
If A is a real matrix no error appears.
Can someone help me?
