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

Create a 64-point Chebyshev window with 100 dB of sidelobe attenuation and display the result using WVTool:

• N=64;
  wvtool(chebwin(N,100)
