triang - Triangular window

Syntax

triang(L)

Description

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

For L odd:

For L even:

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

Examples

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

L=200;
wvtool(triang(L))
