Changes to nzMatrix

New Random Number Generators

This Netezza Analytics release introduces a new set of wrappers on the Intel Math Kernel

Library® random number generators (RNGs). The API provides a set of stored procedures

that generate matrices filled with random values. Following are the new stored procedures:

Stored Procedure Description

CREATE_RANDOM_CAUCHY_MATRIX Create a random matrix using Cauchy distributed ran-

dom values

CREATE_RANDOM_EXPONENT_MATRIX Create a random matrix using Exponential distributed

random values

CREATE_RANDOM_GAMMA_MATRIX Create a matrix of pseudo-random variables following

the Gamma distribution

CREATE_RANDOM_LAPLACE_MATRIX Create a matrix of pseudo-random variables following

the Laplace distribution

CREATE_RANDOM_NORMAL_MATRIX Create a matrix of pseudo-random variables following

the normal distribution

CREATE_RANDOM_POISSON_MATRIX Create a matrix of pseudo-random variables following

the Poisson distribution

CREATE_RANDOM_RAYLEIGH_MATRIX Create a Matrix of random using a Rayleigh distrib-

uted random values generator

CREATE_RANDOM_UNIFORM_MATRIX Create a matrix of pseudo-random variables following

the uniform distribution

CREATE_RANDOM_WEIBULL_MATRIX Create a matrix of pseudo-random variables following

the Weibull distribution
