Imag

Returns the imaginary part of a complex vector in a second vector.

Syntax

IppStatus ippsImag_16sc(const Ipp16sc* pSrc, Ipp16s* pDstIm, int len);

IppStatus ippsImag_32fc(const Ipp32fc* pSrc, Ipp32f* pDstIm, int len);

IppStatus ippsImag_64fc(const Ipp64fc* pSrc, Ipp64f* pDstIm, int len);

pSrc	Pointer to the complex source vector.
pDstIm	Pointer to the destination vector with imaginary parts.
len	Number of elements in the vector.

The function ippsImag is declared in the ipps.h file. This function returns the imaginary part of a complex vector pSrc in the vector pDstIm.

The example below shows how to call the function ippsImag_32fc.

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

void func_imag()

    Ipp32fc pSrc[5] = {{1.2, 3.2}, {0.0, 0.3}, {4.3, 6.7}, {4.2, 0.0}, {1.2, 1.2}};

    Ipp32f pDstIm[5];

    ippsImag_32fc(pSrc, pDstIm, 5);

Result

pDstIm ->(3.2, 0.3, 6.7, 0.0, 1.2)
