AnalysisLibErrType CxMul1D (double arrayXReal[], double arrayXImg[], double arrayYReal[], double arrayYImg[], int numberOfElements, double outputReal[], double outputImg[]);
Multiplies two complex 1D arrays. CxMul1D obtains the element of the resulting complex array using the following formulas:
outputReali = arrayXReali × arrayYReali — arrayXImgi × arrayYImgi
outputImgi = arrayXReali × arrayYImgi + arrayXImgi × arrayYReali
CxMul1D can perform the operations in place; that is, the input and output complex arrays can be the same.
