bartlett

Compute a 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.

Example

w = bartlett(64);
