imdisp is a File Exchange contribution which has been replaced by SC
Be careful if your images are named something img_9.bmp img_10.bmp and so on instead of img_09.bmp img_10.bmp (with fixed number of digits). If you use variable number of digits you will probably want to use https://www.mathworks.com/examples/matlab/community/19425-natsortfiles-examples

sorry some lines were missing in the above code:
dir_in = 'C:\Program Files\hemaMATLAB\R2007b\work\capinput\';
dir_out = 'C:\Program Files\hemaMATLAB\R2007b\work\output\';
file_ext = 'jpg';
listing = dir(strcat(dir_in,'i*.',file_ext));
numfile = length(listing);
>> image_stack = [];
>> for k = 1 : numfile
thisfile = listing(k).name;
thisimage = imread(thisfile);
image_stack(1:size(thisimage,1), 1:size(thisimage,2), :, k) = thisimage;
end
??? Error using ==> imread at 315
File "i1.jpg" does not exist.

Don't use strcat use fullfile instead.
Don't use length use numel instead.
Your error is because you haven't specified the full path of the file in your imread call.
thisimage = imread(fullfile(dir_in, thisfile));
