chebwin

Compute a Chebyshev window

Syntax

w = chebwin(n,r)

Description

w = chebwin(n,r) returns the column vector w containing the length n Chebyshev window whose Fourier transform sidelobe magnitude is r dB below the mainlobe magnitude.

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

Examples

N=64;
w = chebwin(N,100);
plot(w); axis([1 N 0 1]);
