CxMul
AnalysisLibErrType CxMul (double xReal, double xImaginary, double yReal, double yImaginary, double *outputReal, double *outputImaginary);
Purpose
Multiplies two complex numbers, x and y. CxMul obtains the resulting complex number, z, using the following formulas:
zReal = xReal × yReal – xImg × yImg
zImg = xReal × yImg + xImg × yReal
