slu.matrix.getSupernodeStructure
Analyze supernode structure of a matrix.
Syntax
slu.matrix.getSupernodeStructure(A, perm?)
Description
Analyze supernode structure of a matrix. Supernodes are groups of consecutive columns that have the same nonzero pattern below the diagonal. They enable efficient use of BLAS-3 operations during factorization. This is a simplified analysis based on column structure similarity.
Parameters
| Name | Description |
|---|---|
| A | - Sparse matrix in CSC format |
| perm(optional) | - Column permutation (optional) |
Returns
SupernodeStructure
