AnalysisLibErrType ToRect1D (double magnitude[], double phaseRadians[], ssize_t numberOfElements, double outputArrayReal[], double outputArrayImaginary[]);
Purpose
Converts the set of polar coordinate points (magnitude, phase) to a set of rectangular coordinate points (outputReal, outputImg). ToRect1D obtains the ith 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 | ||

| numberOfElements | ssize_t | Number of elements to convert. |
| Output | ||
| Name | Type | Description |
| outputArray_Real | double [] | Real part of the resulting rectangular coordinates. |
| outputArray_Imaginary | double [] | 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. |
