CxGenCosWin

Advanced Analysis Library Only

AnalysisLibErrType CxGenCosWin (NIComplexNumber arrayX[], ssize_t numberOfXElements, double aArray[], int numberOfAElements);

Purpose

Applies a general cosine window to the complex input signal. If a represents aArray and Y represents the output sequence, CxGenCosWin obtains the elements of y using the following equation:

for i = 0, 1, 2, ..., n – 1

where na is the number of coefficients and n is the number of elements in arrayX.

This function performs the window operation in place; that is, the windowed data replaces the input data.

Parameters

Input
Name Type Description
numberOfXElements ssize_t Number of elements in arrayX.
aArray double [] Coefficients used in the general cosine window.
numberOfAElements int Number of elements in aArray.
Output
Name Type Description
arrayX NIComplexNumber [] On input, the input signal.

On output, this parameter returns the input signal with a general cosine window applied.

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.
