Parameters
- pSrc1,pSrc2
- Pointers to the two vectors to be convolved.
- src1Len
- Number of elements in the vectorpSrc1.
- src2Len
- Number of elements in the vectorpSrc2.
- pDst
- Pointer to the vectorpDst. This vector stores the result of the convolution.
- dstLen
- Number of elements in the vectorpDst.
- bias
- Parameter that specifes the starting element of the convolution.
Description
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
.
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepDstorpSrcpointer isNULL.
- ippStsSizeErr
- Indicates an error whensrc1Lenorsrc2Lenis less than or equal to 0.
Example
The example below shows how to call 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
