BlkmanNuttallWin
Advanced Analysis Library Only
AnalysisLibErrType BlkmanNuttallWin (double arrayX[], ssize_t numberOfElements);
Purpose
Applies a Blackman-Nuttall window to a real signal. If y represents the output sequence, BlkmanNuttallWin obtains the elements of y using the following equation:
for i = 0, 1, 2, ..., n – 1
where n is the number of elements in arrayX.
This function applies an unsymmetrical Blackman-Nuttall window to the input signal. If you want to apply a symmetrical Blackman-Nuttall window, call SymWin instead.
This function performs the window operation in place; that is, the windowed data replaces the input data.
Parameters

| Name | Type | Description |
| numberOfElements | ssize_t | The number of elements in arrayX. |
| Output | ||
| Name | Type | Description |
| arrayX | double [] | On input, the input signal. On output, this parameter returns the input signal with a Blackman-Nuttall 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. |
