w = tukeywin(L,r) returns an L-point Tukey window in the column vector, w. A Tukey window is a rectangular window with the first and last r/2 percent of the samples equal to parts of a cosine. See Definitions for the equation that defines the Tukey window. r is a real number between 0 and 1. If you input r ≤ 0, you obtain a rectwin window. If you input r ≥ 1, you obtain a hann window. r defaults to 0.5.

w = tukeywin(L,r)

Tukey WindowsOpen This Example Compute 128-point Tukey windows with five different values of r, or "tapers." Display the results using wvtool. L = 128; t0 = tukeywin(L,0); % Equivalent to a rectangular window t25 = tukeywin(L,0.25); t5 = tukeywin(L); % r = 0.5 t75 = tukeywin(L,0.75); t1 = tukeywin(L,1); % Equivalent to a Hann window wvtool(t0,t25,t5,t75,t1)
