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 isNULL.
- ippStsSizeErr
- Indicates an error whenlenis less than or equal to 0.
