a=imread('smallMozart.tiff'); # the size is 38x25
b=imread('bigMozart.tiff'); # the size is 1140x750
disp(size(b));
disp(size(a));
c=mat2cell(b,[38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38],[25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25]);
for i=1:30
    for j=1:30
        c{i,j}=a;
    end
end
imshow(c)

thanks

You get an error message, if you provide a cell array to the imshow command. Then it i useful to share the message with the readers. It is easier to solve a problem than to guess, what the problem is.

Why do you create c by mat2cell only to overwrite it immediately?

Avoid monsters as:

c=mat2cell(b,[38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38,38],[25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25,25]);

Easier to read:

c = mat2cell(b, repmat(38, 1, 30), repmat(25, 1, 30));

You can simplify:

for i=1:30
    for j=1:30
        c{i,j}=a;
    end
end

to:

c(:) = {a};

imshow does not accept cell arrays as input. It needs a matrix.

Either create this matrix directly:

d = repmat(a, 30, 30);

or join the cell elements:

d = cell2mat(c);
