CREATE_RANDOM_POISSON_MATRIX

This procedure creates a new matrix filled with pseudorandom variables following Poisson distribution using the parameters Lambda and mean 1/Lambda.

Usage

The CREATE_RANDOM_POISSON_MATRIX stored procedure has the following syntax:

CREATE_RANDOM_POISSON_MATRIX(matrixOut,numberOfRows,numberOfCols,lambda)

Paramters

matrixOut: The name of the matrix to be generated.; Type: NVARCHAR(ANY)
numberOfRows: The number of matrix rows.; Type: INT4
numberOfColumns: The number of matrix columns.; Type: INT4
lambda: The value used for lambda.; Type: DOUBLE

Returns

BOOLEAN TRUE if successful.

Details

This procedure uses the MKL library.

Examples

CALL nzm..CREATE_RANDOM_POISSON_MATRIX('A', 5, 10, 1.2345);
CALL nzm..GET_NUM_COLS('A');
CALL nzm..GET_NUM_ROWS('A');
CALL nzm..ANY_NONZERO('A');
CALL nzm..DELETE_MATRIX ('A' );
