Re: [Tftb-help] problem with the use of matlab file

[Eric Chassande-Mottin]

Hi,

i guess you're talking about the script tfrsurf.m
the following lines run smoothly on my computer.

N=256;
sig=fmlin(N,0.1,0.3)+fmlin(N,0.3,0.4)+2*fmlin(N,0.05,0.2).*amgauss(N,190,70);
tfr=tfrwv(sig,1:N,128);
[tfr2,OrderedSurfaces]=tfrsurf(tfr,5,3,1);

please, send a small code evidencing the problem and a detailed
description of your configuration (sysop, matl ver).
