TriWin
Advanced Analysis Library Only
AnalysisLibErrType TriWin (double arrayX[], ssize_t numberOfElements);
Purpose
Applies a triangular window (Barlett window) to a real signal. If y represents the output sequence x, TriWin obtains the elements of y using the following equation:yi = xitri(w)
for i = 0, 1, 2, ..., n – 1
where tri(w) = 1 – |w|, and n is the number of elements in x.
This function performs the window operation in place; that is, the windowed data replaces the input data.
Parameters

| numberOfElements | ssize_t | Number of elements in x. |
| Output | ||
| Name | Type | Description |
| arrayX | double [] | On input, the input signal. On output, this parameter returns the input signal with a triangular 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. |
