CxSub1D

AnalysisLibErrType CxSub1D (double arrayXReal[], double arrayXImg[], double arrayYReal[], double arrayYImg[], int numberOfElements, double outputReal[], double outputImg[]);

Purpose

Subtracts two complex 1D arrays. CxSub1D obtains the element of the resulting complex array using the formulas:

outputReali = arrayXReali – arrayYReali

outputImgi = arrayXImgi – arrayYImgi

CxSub1D can perform the operations in place; that is, the input and output complex arrays can be the same.

Parameters

Input
Name Type Description
arrayXReal double-precision array Real part of the array to subtract from.
arrayXImg double-precision array Imaginary part of the array to subtract from.
arrayYReal double-precision array Real part of the array to subtract.
arrayYImg double-precision array Imaginary part of the array to subtract.
numberOfElements integer Number of elements to subtract.
Output
Name Type Description
outputReal double-precision array Real part of result of the complex array subtraction.
outputImg double-precision array Imaginary part of the result of the complex array subtraction.

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.
