MatLUFactorNumeric
Performs numeric LU factorization of a matrix. Call this routine after first calling MatLUFactorSymbolic().
Synopsis
int MatLUFactorNumeric(Mat mat,Mat *fact)
Collective on Mat
Input Parameters
mat | - the matrix
|
row, col | - row and column permutations
|
Output Parameters
fact -symbolically factored matrix that must have been generated
by MatLUFactorSymbolic()
Notes
See MatLUFactor() for in-place factorization. See
MatCholeskyFactorNumeric() for the symmetric, positive definite case.
Most users should employ the simplified SLES interface for linear solvers
instead of working directly with matrix algebra routines such as this.
See, e.g., SLESCreate().
Keywords
