int MatLUFactorSymbolic(Mat mat,IS row,IS col,double f,Mat *fact)Collective on Mat
mat | - the matrix |
row, col | - row and column permutations |
f | - expected fill as ratio of the original number of nonzeros, for example 3.0; choosing this parameter well can result in more efficient use of time and space. Run with the option -log_info to determine an optimal value to use |
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().
