Method Details

mult

public static void mult(FMatrixSparseCSC A,
 FMatrixSparseCSC B,
 FMatrixSparseCSC C,
 GrowArray<Workspace_MT_FSCC> listWork)

Invoke through CommonOps_MT_FSCC as it will manage the input contract

Performs matrix multiplication. C = A*B. The problem is broken up into as many "blocks" as there are threads available. Each block will process a set of columns independently. After running results from independent blocks are stitched together in the main thread. Extra storage requirements is about the same size as 'C'.

Parameters:

A - Matrix

B - Matrix

C - Storage for results. Array size is increased if needed.

listWork - Storage for internal workspace.
