VectorJaehne

Creates a Jaehne vector.

Syntax

IppStatus ippsVectorJaehne_8u(Ipp8u* pDst, int len, Ipp8u magn);

IppStatus ippsVectorJaehne_8s(Ipp8s* pDst, int len, Ipp8s magn);

IppStatus ippsVectorJaehne_16u(Ipp16u* pDst, int len, Ipp16u magn);

IppStatus ippsVectorJaehne_16s(Ipp16s* pDst, int len, Ipp16s magn);

IppStatus ippsVectorJaehne_32u(Ipp32u* pDst, int len, Ipp32u magn);

IppStatus ippsVectorJaehne_32s(Ipp32s* pDst, int len, Ipp32s magn);

IppStatus ippsVectorJaehne_32f(Ipp32f* pDst, int len, Ipp32f magn);

IppStatus ippsVectorJaehne_64f(Ipp64f* pDst, int len, Ipp64f magn);

Parameters

pDst	Pointer to the destination vector.
len	Number of elements in the vector.
magn	Magnitude of the signal to be generated.

Description

The function ippsVectorJaehne is declared in the ipps.h file. This function creates a Jaehne vector and stores the result in pDst. The magnitude magn must be positive. The function generates the sinusoid with a variable frequency. The computation is performed as follows:

pDst[n] = magn * sin ((0.5πn²)/len), 0 ≤ n < len

The example below shows how to use the function ippsVectorJaehne.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pSrcDst pointer is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
ippStsJaehneErr	Indicates an error when magn is negative.

Using the ippsVectorJaehne Function

IppStatus Jaehne (void)
{

    Ipp16s buf[100] ;

    return ippsVectorJaehne_16s ( buf, 100, 255 );
