SUBTRACT

This procedure computes C = A - B, where A, B, and C are matrices.

Usage

The SUBTRACT stored procedure has the following syntax:

SUBTRACT(matrixA,matrixB,matrixC)

Parameters

matrixA: The name of input matrix A.; Type: NVARCHAR(ANY)
matrixB: The name of input matrix B.; Type: NVARCHAR(ANY)
matrixC: The name of output matrix C.; Type: NVARCHAR(ANY)

Returns

BOOLEAN TRUE always.

Examples

call nzm..shape('1,2,3,4,5,6,7,8,9,0',3,3,'A'); 
call nzm..shape('0,9,8,7,6,5,4,3,2,1',3,3,'B'); 
call nzm..subtract('A','B','C'); 
call nzm..print('C');
call nzm..delete_matrix('A');
call nzm..delete_matrix('B');
call nzm..delete_matrix('C');
