MIN - elementwise minimum, elementwise logical AND

This procedure implements an elementwise computation of C := min(A,B), where A, B, and C are matrices.

Usage

The MIN stored procedure has the following syntax:

MIN(matrixAname,matrixBname,matrixCname)

Parameters

matrixAname: The name of input matrix A.; Type: NVARCHAR(ANY)
matrixBname: The name of input matrix B.; Type: NVARCHAR(ANY)
matrixCname: The name of output matrix C.; Type: NVARCHAR(ANY)

Returns

BOOLEAN TRUE, if successful.

Details

If matrices A and B are logical matrices consisting of zeros (0) as FALSE and ones (1) as TRUE, then C := A | B (elementwise "AND"). Matrices A and B must have the same dimensions, that is, the same number of rows and columns. Matrix C is given the same shape. Matrix C must not exist prior to the operation.

Examples

CALL nzm..SHAPE('1,2,3,4,5,6,7,8,9',3,3,'A');
CALL nzm..SHAPE('9,8,7,6,5,4,3,2,1',3,3,'B');
CALL nzm..MIN('A','B','C');
CALL nzm..PRINT('C');
CALL nzm..DELETE_MATRIX('A');
CALL nzm..DELETE_MATRIX('B');
CALL nzm..DELETE_MATRIX('C');
