Real

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

Syntax

IppStatus ippsReal_16sc(const Ipp16sc* pSrc, Ipp16s* pDstRe, int len);

IppStatus ippsReal_32fc(const Ipp32fc* pSrc, Ipp32f* pDstRe, int len);

IppStatus ippsReal_64fc(const Ipp64fc* pSrc, Ipp64f* pDstRe, int len);

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

The function ippsReal is declared in the ipps.h file. This function returns the real part of the complex vector pSrc in the vector pDstRe.

The example below shows how to call the function ippsReal_32fc.

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

void func_real()

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

    Ipp32f pDstRe[5];

    ippsReal_32fc(pSrc,pDstRe,5);

Result

pDestRe ->(1.2, 0.0, 4.3, 4.2, 1.2)
