winwrite(H,'filename') saves the values of the Tukey window object H in the current folder as a column vector in the ASCII file 'filename'. The file extension .wf is automatically appended to filename.

Examples

Tukey Windows

Generate two Tukey windows of length N = 64:

• The first window has α = 1/4. α is the ratio of tapered window section length to constant section length.

• The second window has α = 3/4.

Display the two windows.

H14 = sigwin.tukeywin(64,1/4);
H34 = sigwin.tukeywin(64,3/4);

wvt = wvtool(H14,H34);
legend(wvt.CurrentAxes,'\alpha = 1/4','\alpha = 3/4')

Generate a Tukey window with length N = 16 and the default α = 1/2. Return its values as a column vector. Show information about the window object. Display the window.

H = sigwin.tukeywin(16);

win = generate(H)

win = 16×1
