hello.. iam stuck over here on function gabor
function [out1 out2] = fn_gabor(c)
alpha = 1/sqrt(2);
t=1;
for teta = pi/8:pi/8:pi;
for j = 2:5;
for x = -8:8;
for y = -8:8;
h = exp((-alpha^(2*j))*(x^2 + y^2)/2);
HI (x+9,y+9)= h;
Re = cos (pi*(alpha^j)*(x*cos(teta)+ y*sin(teta)));
RI (x+9,y+9)= Re;
Im = sin (pi*(alpha^j)*(x*cos(teta)+ y*sin(teta)));
II (x+9,y+9)= Im;
end;
end;
Rh = HI*RI;
Rh;
Ih = HI*II;
Ih;
R = conv(in,Rh); %%%ERROR IN HERE
I = conv(in,Ih);
% Normalisasi
Ro = (R)/(max(max(R)));
Roa = mean (Ro);
Roav = mean (Roa);
Io = (I)/(max(max(I)));
Ioa = mean (Io);
Ioav = mean (Ioa);
% Magnitude hasil konvolusi
out = sqrt (Ro*Ro' + Io*Io');
outfil(t) = sqrt (Roav*Roav + Ioav*Ioav);
t = t + 1;
end;
end;
out1 = out;
out2 = outfil;
please help.. thank you..

Well the reason is that you haven't defined 'in' anywhere.
My guess is that the input variable should be named 'in'. You haven't used the input 'c' anywhere in your function.

so supposed to replace the variable 'in' in the code is? because function 'conv' is a vector
