    f=imread('Image.jpeg');
red=f(:,:,1);
[r,c]=size(red)
z=zeros(r,c);
for i=1:r
    for j=1:c
        z(i,j)=dec2hex(red(i,j))
    end
end

This code gives me an error 'Subscripted assignment dimension mismatch.' in line 7. I can't figure out why?

dec2hec results in a char array of 1*n for each (i,j) pair, which then would not fit into one element of the numeric array z.

Depends on what you want to use z for, you could consider changing the shape.
