triang

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).

Example

w = triang(200);
plot(w)
