ConvBiased

Computes the specified number of elements of the full finite linear convolution of two vectors.

Syntax

IppStatus ippsConvBiased_32f(const Ipp32f* pSrc1, int src1Len, const Ipp32f* pSrc2, int src2Len, Ipp32f* pDst, int dstLen, int bias);

Parameters

pSrc1, pSrc2	Pointers to the two vectors to be convolved.
src1Len	Number of elements in the vector pSrc1.
src2Len	Number of elements in the vector pSrc2.
pDst	Pointer to the vector pDst. This vector stores the result of the convolution.
dstLen	Number of elements in the vector pDst.
bias	Parameter that specifes the starting element of the convolution.

Description

The function ippsConvBiased is declared in the ipps.h file. This function computes dstLen elements of finite linear convolution of two specified vectors pSrc1 and pSrc2 starting with an element that is specified by the bias. The result is stored in the vector pDst.

The example below shows how to call the function ippsConvBiased.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pDst or pSrc pointer is NULL.
ippStsSizeErr	Indicates an error when src1Len or src2Len is less than or equal to 0.

Using the Function ippsConvBiased

void func_convbiased()

    Ipp32f pSrc1[5] = {1.1, -2.0, 3.5, 2.2, 0.0};

    Ipp32f pSrc2[4] = {0.0, 0.2, 2.5, -1.0};

    const int len = 10;

    Ipp32f pDst[len];

    int bias = 1;

    ippsZero_32f(pDst, len);

    ippsConvBiased_32f(pSrc1, 5, &pSrc2[1], 3, pDst, len, bias);

Result:

        pDst -> 0.2  2.3  -4.3  9.2  5.5  0.0  0.0  0.0  0.0  0.0
