Method Details

multTranspose

public static CNumber[] multTranspose(CNumber[] dSrc,
 Shape dShape,
 CNumber[] spSrc,
 int[] rowIndices,
 int[] colIndices,
 Shape spShape)

Multiplies a complex dense matrix to the transpose of a complex sparse matrix.

Parameters:

dSrc - Entries of dense matrix.

dShape - Shape of dense matrix.

spSrc - Non-zero entries of sparse matrix.

rowIndices - Row indices of non-zero entries in the sparse matrix.

colIndices - Column indices of non-zero entries in the sparse matrix.

spShape - Shape of the sparse matrix.

Returns:

The entries of the matrix resulting from multiplying the first matrix by the transpose of the second matrix.
