Ran in:
Read the individual cell array data element, apply image function
% cell_element=....
% image(cell_element)
% axis off;
You might be required to use loop to call the individual cell array data element. Later it can be save as image in the directory or any other ways, you wish for.
Example:
data=randi(500,500);
image(data)
axis off;
Hope it helps!

ok, still you can separate real and complex part of data and visualize with image function.
image(real(data));
image(imag(data));
image(abs(data));
