Bartlett window

Syntax

```
w = bartlett(n)
```

Description

w = bartlett(n) returns an n-point Bartlett window in the column vector w, where n must be a positive integer. The coefficients of a Bartlett window are computed as follows:

For n odd

For n even

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

Note If you specify a one-point window (set n=1), the value 1 is returned.

Examples

Create a 64-point Bartlett window and display the result using WVTool:

```
N=64;
wvtool(bartlett(N))
```
