RandGaussInit

Initializes a noise generator with Gaussian distribution.

Syntax

IppStatus ippsRandGaussInit_16s(IppsRandGaussState_16s* pRandGaussState, Ipp16s mean, Ipp16s stdDev, unsigned int seed);

Parameters

pRandGaussState	Pointer to the structure containing parameters for the generator of noise.
mean	Mean of the Gaussian distribution.
stdDev	Standard deviation of the Gaussian distribution.
seed	Seed value used by the pseudo-random number generator algorithm.

Description

The function ippsRandGaussInit is declared in the ipps.h file. This function initializes the pseudo-random generator state structure pRandGaussState in the external buffer. The size of this buffer must be computed previously by calling the function ippsRandGaussGetSize. This structure contains parameters of the required noise generator that are specified by the mean, stdDev and seed values.

Return Values

ppStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pRandGaussState pointer is NULL.
ippStsMemAllocErr	Indicates an error when there is not enough memory for the operation.
