slu.analysis.predictFillIn
Predict fill-in for LU factorization.
Syntax
slu.analysis.predictFillIn(A, perm)
Description
Predict fill-in for LU factorization. Computes column counts for L and row counts for U, which determine the fill-in pattern without performing numerical factorization. This is useful for memory allocation and comparing ordering strategies.
Parameters
| Name | Description |
|---|---|
| A | - Sparse matrix in CSC format |
| perm | - Column permutation |
Returns
