CxMul1D

AnalysisLibErrType CxMul1D (double arrayXReal[], double arrayXImaginary[], double arrayYReal[], double arrayYImaginary[], ssize_t numberOfElements, double outputArrayReal[], double outputArrayImag[]);

Purpose

Multiplies two complex 1D arrays. CxMul1D obtains the ith 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.

Parameters

Input
Name Type Description
arrayX_Real double [] Real part of the first array to multiply.
arrayX_Imaginary double [] Imaginary part of the first array to multiply.
arrayY_Real double [] Real part of the second array to multiply.
arrayY_Imaginary double [] Imaginary part of the second array to multiply.
numberOfElements ssize_t Number of elements to multiply.
Output
Name Type Description
outputArray_Real double [] Real part of the result of the complex array multiplication.
outputArray_Imag double [] Imaginary part of the result of the complex array multiplication.

Return Value

Name Type Description
status AnalysisLibErrType A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants.
