How can I use a matrix to be a loop variable

For example, in usual for loop, it looks like that
for i=1:1:10
disp(i)
end
if I want the variable to be a matrix,like:
for mat = set of matrices
imshow(mat);
end
the set of matrices is composed of {mat1,mat2,mat3,mat4}

I don't believe it's possible for a for loop index to be larger than a 1x1 size. That doesn't mean though that it's not possible to use the matrices within your loop. How are your matrices related? What type of organization do you have for them?

If you have somethign like
mat = {mat1,mat2,mat3,mat4}
You can do
for m = 1:numel(mat)
imshow(mat{m})
end

Wow, thank you very much, this is just so convenient.
Also, I found another method, like
matlis=mat1;
matlis(:,:,2)=mat2;
matlis(:,:,3)=mat3;
for i=1:3
figure
imshow(malis(:,:,i))
end
but this is not as concise as your solutionm, thanks again!
You can also do
for m = {mat1, mat2, mat3, mat4}
figure()
imshow(m{1})
end
