CxSub

AnalysisLibErrType CxSub (double xReal, double xImg, double yReal, double yImg, double *zReal, double *zImg);

Purpose

Subtracts two complex numbers, x and y. The resulting complex number, z, is obtained using the following formulas:

zReal = xReal – yReal

zImg = xImg – yImg

Parameters

Input
Name Type Description
xReal double-precision Real part of the first complex number to subtract.

xImg double-precision Imaginary part of the first complex number to subtract.

Default Value: 0.0
yReal double-precision Real part of the second complex number to subtract.

Default Value: 0.0.
yImg double-precision Imaginary part of the second complex number to subtract.

Default Value: 0.0
Output
Name Type Description
zReal double-precision Real part of the result of the complex subtraction.
zImg double-precision Imaginary part of the result of the complex subtraction.
