GenCosWin

Advanced Analysis Library Only

AnalysisLibErrType GenCosWin (double XArray[], int numberXElements, double A_Array[], int numberAElements);

Purpose

Applies a general cosine window to the input signal. If Y represents the output sequence, GenCosWin obtains the elements of Y using the following formula:

where a is the array of coefficients
na is the number of coefficients
n is the number of elements in XArray

Parameters

Input
Name Type Description
numberXElements integer Number of elements in the input array, XArray.
A_Array double-precision array Coefficients used in the General Cosine Window.
numberAElements integer Number of elements in A_Array.
Output
Name Type Description
XArray double-precision array On input, the input signal.

On output, the signal after GenCosWin applies the general cosine window.

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.
