I want to use the imshow function and set function (both of them) with the MATLAB subplot function to display multiple images in a single figure window. But because of the set function in the following code, it isn't possible. How to solve it?

if str2num(N1(1:end-4)) == str2num(N2(1:end-4))
    subplot(1,2,1);
    imshow(volume_image(:, :, i), []);
    green = cat(3, zeros(size(volume_image(:, :, i))), ones(size(volume_image(:, :, i))), zeros(size(volume_image(:, :, i))));
    subplot(1,2,2);
    h = imshow(green);            
    set(h, 'AlphaData', double(Rad_Img));
end

You are missing a ) in the set command.

@Walter Roberson: Yes, it occurred during edition, but the problem isn't because of it.

AlphaData must be in the range 0 to 1. I suspect your Rad_Img is uint8, range 0 to 255; if so then double() would produce 0.0 to 255.0 instead of 0 to 1. Perhaps

set(h, 'AlphaData', im2double(Rad_Img));

@Walter Roberson: I have tried it, but I want to show Fig1 image and the final image after set(h, 'AlphaData', double(Rad_Img)) in a single figure window. Then, the subplot is needed.
