element of the rectangular set using the following formulas:AnalysisLibErrType ToRect1D (double magnitude[], double phase[], int numberOfElements, double outputReal[], double outputImg[]);
Converts the set of polar coordinate points (magnitude, phase) to a set of rectangular coordinate points (outputReal, outputImg). ToRect1D obtains the element of the rectangular set using the following formulas:
outputReali = magnitudei × cos(phasei)
outputImgi = magnitudei × sin(phasei)
ToRect1D can perform the operations in place; that is, the input and output arrays can be the same.
