LN_ELEMENTS - elementwise LN function

This procedure implements an elementwise natural log calculation for the specified block of elements.

Usage

The LN_ELEMENTS stored procedure has the following syntax:
LN_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.
Type: INT4
col_start
The first column of the input matrix to use.
Type: INT4
row_stop
The last row of the input matrix to use.
Type: INT4
col_stop
The last column of the input matrix to use.
Type: INT4
Returns
BOOLEAN TRUE, if successful.

Examples

CALL nzm..SHAPE('1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16',4,4,'A'); 
CALL nzm..LN_ELEMENTS('A', 'B', 2, 2, 3, 3); 
CALL nzm..PRINT('B');
CALL nzm..DELETE_MATRIX('A');
CALL nzm..DELETE_MATRIX('B');
