tfrsave

Save the parameters of a time-frequency representation

Calling Sequence

tfrsave(NAME, TFR, METHOD, SIG, T, F, P1, P2, P3, P4, P5)

Parameters

NAME :

name of the mat-file (less than 8 characters).

TFR :

time-frequency representation (MxN).

METHOD :

chosen representation.

SIG :

signal from which the TFR was obtained

T :

time instant(s) (default : (1:N)).

F :

frequency bins (default : linspace(0,0.5,M)).

P1..P5 :

optional parameters : run the file tfrparam(METHOD) to know the meaning of P1..P5 for your method.

Description

tfrsave saves the parameters of a time-frequency representation in the file NAME.dat. Two additional parameters are saved : TfrQView and TfrView. If you load the file 'name.dat' and do execstr(TfrQView), you will restart the display session under tfrqview ; if you do execstr(TfrView), you will display the representation by means of tfrview.

Examples

sig = fmlin(64);
tfr = tfrwv(sig);
tfrsave('wigner',tfr,'TFRWV',sig,1:64);
clear sig tfr
load 'wigner.dat'; execstr(TfrQView);
