Parameters
pSrc |
Pointer to the source vector. |
pDst |
Pointer to the destination vector. |
pSrcDst |
Pointer to the source and destination vector (for the in-place operation). |
lenDst |
Number of elements in the vector. |
Description
This function converts the data in CCS format in the vector pSrc to complex data format and stores the results in pDst.
The in-place function ippsConjCcs converts the data in CCS format in the vector pSrcDst to complex data format and stores the results in pSrcDst.
The following table shows the examples of unpack from the CCS format. The Data column contains the real input data to be converted by the forward FFT transform to the packed data. The packed real data are in the Packed column. The output result is the complex data vector in the Extended column. The number of vector elements is in the Length column. The data stored in CCS format are two real elements longer.
Data | Packed | Extended | Length |
---|---|---|---|
FFT([1]) | 1, 0 | {1, 0} | 1 |
FFT([1 2]) | 3, 0, -1, 0 | {3, 0}, {-1, 0} | 2 |
FFT([1 2 3]) | 6, 0, -1.5, 0.86 | {6, 0}, {-1.5, 0.86}, {-1.5, -0.86} | 3 |
FFT([1 2 3 9]) | 15, 0, -2, 7, -7, 0 | {15, 0}, {-2, 7}, {-7, 0}, {-2, -7} | 4 |
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when the pSrcDst, pDst, or pSrc pointer is NULL. |
ippStsSizeErr |
Indicates an error when lenDst is less than or equal to 0. |
