求教Matlab的 gabor变换
N1=512;fs=2000;
t=(0:N1-1)/fs;
Fm=zeros(3,length(t));
F=0;
f=;
A=;
d=;
for m=1:3;
Fm(m,: )=A(m)*exp(-3.14*d(m)*t+i*(2*pi*f(m)*t));
end
F=sum(Fm);
F=F+awgn(F,inf);
FR=real(F);
plot(FR);
Q=1;
N=32;
Nh=39;
%tt=(0:N-1)/fs;
%h1=exp(-3.14*15*tt);
g=window(@gausswin,Nh); %如何用以指数衰减的函数做窗函数啊？50486
g=g/norm(g);
=tfrgabor(FR,N,Q,g);
