LN_ELEMENTS - elementwise LN function (entire matrix operation)

This procedure implements an elementwise natural log calculation.

Usage

The LN_ELEMENTS stored procedure has the following syntax:

LN_ELEMENTS(matrixIn,matrixOut)

Parameters

matrixIn: The name of the input matrix.; Type: NVARCHAR(ANY)
matrixOut: The name of the output matrix.; Type: NVARCHAR(ANY)

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'); 
CALL nzm..PRINT('B');
CALL nzm..DELETE_MATRIX('A');
CALL nzm..DELETE_MATRIX('B');
