triang (Signal Processing Toolbox)

Compute a triangular window

Syntax

```
w = triang(n)
```

Description

triang(n) returns an n-point triangular window in the column vector w. The coefficients of a triangular window are:

For n odd:

For n even:

The triangular window is very similar to a Bartlett window. The Bartlett window always ends with zeros at samples 1 and n, while the triangular window is nonzero at those points. For n odd, the center n-2 points of triang(n-2) are equivalent to bartlett(n).

Examples

Create a 200-point triangular window and plot the result using WVTool.

```
N=200;
wvtool(triang(N)) 
```
