winwrite

Class: sigwin.hann
Package: sigwin

Save Hann window object values in ASCII file

Syntax

winwrite(H)
winwrite(H,'filename')

Description

winwrite(H) opens a dialog to export the values of the Hann window object H to an ASCII file. The file extension .wf is automatically appended.

winwrite(H,'filename') saves the values of the Hann 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

expand all

Generate two Hann windows:

  • The first window has N = 64 and is symmetric.

  • The second window has N = 63 and is periodic.

Display the two windows.

Hs = sigwin.hann(64,'symmetric');
Hp = sigwin.hann(63,'periodic')
Hp = 
            Name: 'Hann'
    SamplingFlag: 'periodic'
          Length: 63

wvt = wvtool(Hs,Hp);
legend(wvt.CurrentAxes,'Symmetric','Periodic')

Generate a symmetric Hann window with N = 16. Return the window values as a column vector. Show information about the window object. Display the window.

H = sigwin.hann(16);

win = generate(H)
win =
