# ToRect1D

AnalysisLibErrType ToRect1D (double magnitude[], double phase[], int numberOfElements, double outputReal[], double outputImg[]);

## Purpose

Converts the set of polar coordinate points (magnitude, phase) to a set of rectangular coordinate points (outputReal, outputImg). ToRect1D obtains the element of the rectangular set using the following formulas:

outputReali = magnitudei × cos(phasei)

outputImgi = magnitudei × sin(phasei)

ToRect1D can perform the operations in place; that is, the input and output arrays can be the same.

## Parameters

Input
Name | Type | Description
magnitude | double-precision array | Magnitude of the polar coordinates to convert to rectangular coordinates.
phase | double-precision array | Phase, in radians, of the polar coordinates to convert to rectangular coordinates.
numberOfElements | integer | Number of elements to convert.
Output
Name | Type | Description
outputReal | double-precision array | Real part of the resulting rectangular coordinates.
outputImg | double-precision array | Imaginary part of resulting the rectangular coordinates.

## 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.
