RandUniform

Generates the pseudo-random samples with a uniform distribution in direct mode.

Syntax

IppStatus ippsRandUniform_Direct_16s(Ipp16s* pDst, int len, Ipp16s low, Ipp16s high, unsigned int* pSeed);

IppStatus ippsRandUniform_Direct_32f(Ipp32f* pDst, int len, Ipp32f low, Ipp32f high, unsigned int* pSeed);

IppStatus ippsRandUniform_Direct_64f(Ipp64f* pDst, int len, Ipp64f low, Ipp64f high, unsigned int* pSeed);

Parameters

pSeed	Pointer to the seed value used by the pseudo-random number generation algorithm.
low	Lower bound of the uniform distribution range.
high	Upper bound of the uniform distribution range.
pDst	Pointer to the array which stores the samples.
len	Number of samples to be computed.

Description

The function ippsRandUniform_Direct is declared in the ipps.h file. This function generates len pseudo-random samples with a uniform distribution and stores them in the array pDst. This function does not require to initialize the generator state structure in advance. All parameters of the pseudo-random number generator are set directly in the function.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pDst or pSeed pointer is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
