GaussWin
Advanced Analysis Library Only
AnalysisLibErrType GaussWin (double arrayX[], ssize_t numberOfElements, double standardDeviation);
Purpose
Applies a Gaussian window to a real signal. If y represents the output sequence arrayX, GaussWin obtains the elements of y using the following equation:
where n is the number of elements in arrayX and σ is the standard deviation of the Gaussian window.
This function applies an unsymmetric Gaussian window on the input signal. If you want to use a symmetric Gaussian window, call SymWin instead.
This function performs the window operation in place; that is, the windowed data replaces the input data.
Parameters
| Input | ||
| Name | Type | Description |
| numberOfElements | ssize_t | The number of elements in arrayX. |
| standardDeviation | double | The standard deviation of the Gaussian window normalized to the length of arrayX. The default value is 0.2. If standardDeviation <= 0, the default value is used. |
| Output | ||
| Name | Type | Description |
| arrayX | double [] | On input, the input signal. On output, this parameter returns the input signal with a Gaussian 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. |
