mkl_sparse_optimize

Analyzes matrix structure and performs optimizations using the hints provided in the handle.

Syntax

stat = mkl_sparse_optimize (A)

Include Files

  • mkl_spblas.f90

Description

The mkl_sparse_optimize routine analyzes matrix structure and performs optimizations using the hints provided in the handle. Generally, specifying a higher number of expected operations allows for more aggressive and time consuming optimizations.
