topic how about pSeed value? in Intel® Integrated Performance Primitives

RandUniform issue

Isaac_D_ — Mon, 10 Feb 2014 14:32:28 GMT

Hello,

I'm trying to use the function ippsRandUniform_Direct_64f, but I can't obtain anything, I just get a vector full of zeros. Here is the function I'm using, maybe there's something wrong with the code. Hope you'll help me.

#include "stdafx.h"
#include "ipp.h"
#pragma warning (disable:4996)

static unsigned int *pSeed;

extern "C"{

_declspec(dllexport) void nnlsbp_1D(double u[]);
}
_declspec(dllexport) void nnlsbp_1D(double u[]){

ippsRandUniform_Direct_64f(u,91,0,1,pSeed);

}

how about pSeed value?

Hi Isaac,

Hi Isaac,

first of all I reccomend you to use correct syntax while calling IPP - to use IppStatus and check it after a call - guess for this particular example you'll get ippStsNullPtrErr = -8, /* Null pointer error. */ as pSeed pointer is not initialized...
