CxLn
Advanced Analysis Library Only
AnalysisLibErrType CxLn (double xReal, double xImaginary, double *outputReal, double *outputImaginary);
Purpose
Calculates the natural logarithm of a complex number. CxLn obtains the resulting complex number using the following formula:
(outputReal, outputImg) = loge(xReal, xImg)
where e = 2.178 . . .
