My code:
load ('cl.dat')
c=reshape(cl,106,14)
ct=transpose(c)
imagesc(ct)
imwrite(ct,'f8.jpg','jpg')
I just want to save the image but it does not work,where is the problem?

"where is the problem?" - I was going to ask you the same thing. What does "it does not work" mean? Do you have an error message? Are you sure ct is uint8? What does
whos ct
report back?

mat2gray scales to 0-1 so you might need to use
ctUint8 = uint8(255*mat2gray(ct));
if you want it to look bright with a normal gray scale colormap.
Posting an image would help. I don't know what "clusters" means to you. Do you want to do image classification?
