AnalysisLibErrType HanWin (double arrayX[], int numberOfElements);
Applies a Hanning window to the input signal. The following formula defines the Hanning window:
for i = 0, 1, . . ., n 1
HanWin obtains the output signal using the following formula:
xi = xi × wi
for i = 0, 1, . . ., n 1
HanWin performs the window operation in place; that is, the windowed data replaces the input data.
