ImplMultiplicationWithSemiRing_DSCC

public ImplMultiplicationWithSemiRing_DSCC()

Method Details

mult

public static void mult(DMatrixSparseCSC A,
 DMatrixSparseCSC B,
 DMatrixSparseCSC C,
 DSemiRing semiRing,
 @Nullable
 @Nullable Mask mask,
 @Nullable
 @Nullable IGrowArray gw,
 @Nullable
 @Nullable DGrowArray gx)

Performs matrix multiplication. C = A*B

Parameters:

A - Matrix

B - Matrix

C - Storage for results. Data length is increased if increased if insufficient.

mask - (Optional) Mask for specifying which entries should be overwritten

gw - (Optional) Storage for internal workspace. Can be null.

gx - (Optional) Storage for internal workspace. Can be null.

multAddColA

public static void multAddColA(DMatrixSparseCSC A,
 int colA,
 double alpha,
 DMatrixSparseCSC C,
 int mark,
 DSemiRing semiRing,
 @Nullable
 @Nullable Mask mask,
 double[] x,
 int[] w)

Performs the operation x = x + A(:,i)*alpha

NOTE: This is the same as cs_scatter() in csparse.
