triang

Triangular window

collapse all in page

Syntax

w = triang(L)

Description

example

w = triang(L) returns an L-point triangular window.

Examples

collapse all

Open Live Script

Create a 200-point triangular window. Display the result using wvtool.

L = 200;
w = triang(L);
wvtool(w)

Input Arguments

collapse all

Window length, specified as a positive integer.

Data Types: single | double

Output Arguments

collapse all

Triangular window, returned as a column vector.

Algorithms

The coefficients of a triangular window are:

For L odd:

w(n)={2nL+11≤n≤L+122−2nL+1L+12+1≤n≤L

For L even:

w(n)={(2n−1)L1≤n≤L22−(2n−1)LL2+1≤n≤L
