Hi,
imshow(image1); hold
himage=imshow(image2);
set(himage, 'AlphaData', 0.3); % 0.3 control transparent behavior, 1=Not Transparent.
This Code show image1 and then image2 in one figure with Image2 is transparent and control with number, 0.3 here.
How to save the current figure ( Combination of Image1 and Image2) into some variable to be used later in workspace.
Regards.

If you are trying to create a data array that is the two images combined with the upper one alpha 0.3, then especially if the images are the same size, the easiest way is to do the calculation yourself.
alphaval = 0.3;
image1d = im2double(image1); %use 0 to 1 range
image2d = im2double(image2); %use 0 to 1 range
combined = image1d .* (1-alphaval) + image2d .* alphaval;
The above code has the advantage of working even if the images were not originally the same data class.
If the images are originally the same data class, then you do not strictly need to covert to double, but you get better accuracy if you do.
