ToRect
AnalysisLibErrType ToRect (double magnitude, double phaseRadians, double *xReal, double *xImaginary);
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

| Name | Type | Description |
| magnitude | double | Magnitude portion of the polar representation of a complex number. Default Value: 0.0. |
| phase_Radians | double | Phase portion, in radians, of a polar representation of a complex number. |
| Output | ||
| Name | Type | Description |
| x_Real | double | Real part of the rectangular representation of a complex number. |
| x_Imaginary | double | Imaginary part of the rectangular representation of a complex number. |
Return Value
