winwrite
Class: sigwin.nuttallwin
Namespace: sigwin
Save Nuttall defined four-term Blackman-Harris window object values in ASCII file
Syntax
winwrite(H)
winwrite(H,'filename')
Description
winwrite(H) opens a dialog box to export the values of the Nuttall
defined four-term Blackman-Harris window object H to an ASCII file.
The file extension .wf is automatically appended.
winwrite(H,'filename') saves the values
of the Nuttall defined four-term Blackman-Harris 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
Generate two Nuttall-defined four-term Blackman-Harris 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.nuttallwin(64); Hp = sigwin.nuttallwin(63); Hp.SamplingFlag = 'periodic'; wvt = wvtool(Hs,Hp); legend(wvt.CurrentAxes,'Symmetric','Periodic')
Generate a symmetric Nuttall-defined four-term Blackman-Harris window with N = 16. Return the window values as a column vector. Show information about the window object. Display the window.
H = sigwin.nuttallwin(16); win = generate(H)
win = 16×1
