ToRect

AnalysisLibErrType ToRect (double magnitude, double phase, double *xReal, double *xImg);

Purpose

Converts the polar coordinates (magnitude, phase) to rectangular coordinates (xReal, xImg). ToRect obtains the rectangular coordinates using the following formulas:

xReal = magnitude × cos(phase)

xImg = magnitude × sin(phase)

Parameters

Input
Name Type Description
magnitude double-precision Magnitude portion of the polar representation of a complex number.

Default Value: 0.0.
phase double-precision Phase portion, in radians, of a polar representation of a complex number.
Output
Name Type Description
xReal double-precision Real part of the rectangular representation of a complex number.
xImg double-precision Imaginary part of the rectangular representation of a complex number.

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.
