ABS_ELEMENTS - elementwise ABS

This procedure implements the element wise absolute value calculation for the specified block of elements.

Usage

The ABS_ELEMENTS stored procedure has the following syntax:

ABS_ELEMENTS('matrixIn','matrixOut',row_start,col_start,row_stop,col_stop)
Parameters
matrixIn
The name of the input matrix.
Type: NVARCHAR(ANY)
matrixOut
The name of the output matrix.
Type: NVARCHAR(ANY)
row_start
The first row of the input matrix to use for the calculation.
Type: INT4
col_start
The first column of the input matrix to use for the calculation.
Type: INT4
row_stop
The last row of the input matrix to use for the calculation.
Type: INT4
col_stop
The last column of the input matrix to use for the calculation.
Type: INT4
Returns
BOOLEAN TRUE, if successful.

Examples

CALL nzm..SHAPE('-1.0', 4, 4, 'A');
CALL nzm..ABS_ELEMENTS('A', 'B', 2, 2, 3, 3);
CALL nzm..PRINT('A');
CALL nzm..PRINT('B');
CALL nzm..DELETE_MATRIX('A' );
CALL nzm..DELETE_MATRIX('B' );
