Parameters

pSrcMagn	Pointer to the source vector which stores the magnitude (radius) components of the elements in polar coordinate form.
pSrcPhase	Pointer to the vector which stores the phase (angle) components of the elements in polar coordinate form in radians.
pDst	Pointer to the resulting vector which stores the complex pairs in Cartesian coordinates (X + iY).
pDstRe	Pointer to the resulting vector which stores the real components of Cartesian X,Y pairs.
pDstIm	Pointer to the resulting vector which stores the imaginary components of Cartesian X,Y pairs.
len	Number of elements in the vectors.
phaseFixedPoint	Specified the position of the decimal fixed point for the phase.
magnScaleFactor	Integer scale factor for the magnitude component, refer to Integer Scaling.
phaseScaleFactor	Integer scale factor for the phase component, refer to Integer Scaling.

Description

The function ippsPolarToCart is declared in the ipps.h file. This function converts the polar form magnitude/phase pairs stored in the input vectors pSrcMagn and pSrcPhase into a complex vector and stores the results in the vector pDst, or stores the real components of the result in the vector pDstRe and the imaginary components in the vector pDstIm.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
