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.

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

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.
