GEMM - general matrix multiplication

This procedure computes the general matrix multiplication C = AB, where A, B, C are matrices.

Usage

The GEMMA stored procedure has the following syntax:

GEMMA(matrixA,transposeA,matrixB,transposeB,matrixC)

Parameters

matrixA: The name of the input matrix A.; Type: NVARCHAR(ANY)
transposeA: Specifies whether matrix A should be transposed for multiplication.; Type: BOOLEAN
matrixB: The name of the input matrix B.; Type: NVARCHAR(ANY)
transposeB: Specifies whether matrix B should be transposed for multiplication.; Type: BOOLEAN
matrixC: The name of the output matrix C.; Type: NVARCHAR(ANY)

Returns

BOOLEAN TRUE always.

Examples

CALL nzm..shape('1,2,3,4,5,0,6,7,8', 3, 3, 'A'); 
CALL nzm..shape('2,2,2,3,3,3,4,4,4', 3, 3,'B'); 
CALL nzm..gemm('A', FALSE,'B', TRUE,'C'); 
CALL nzm..print('C');
CALL nzm..delete_matrix('A');
CALL nzm..delete_matrix('B');
CALL nzm..delete_matrix('C');
