tfrqview

Quick visualization of time-frequency representations

Calling Sequence

tfrqview(TFR, SIG, T, METHOD, P1, P2, P3, P4, P5)

Parameters

TFR :

time-frequency representation (MxN).

SIG :

signal in time. If unavailable, put sig=[] as input parameter. (default : []).

T :

time instants (default : 1:N).

METHOD :

name of chosen representation (default : 'TYPE1').

tfr* :

See the help for authorized names.

TYPE1 :

the representation TFR goes in normalized frequency from -0.5 to 0.5 ;

TYPE2 :

the representation TFR goes in normalized frequency from 0 to 0.5.

P1...P5 :

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

Description

tfrqview allows a quick visualization of a time-frequency representation. When you use the 'save' option in the main menu, you save all your variables as well as two strings, TfrQView and TfrView, in a mat file. If you load this file and do eval(TfrQView), you will restart the display session under tfrqview ; if you do eval(TfrView), you will obtain the exact layout of the screen you had when clicking on the 'save' button.

Examples

sig = fmsin(128);
tfr = tfrwv(sig);
tfrqview(tfr,sig,1:128,'tfrwv');
