% Load entire mat file contents into a structure. % The structure has a member "I" that is a double 512x512 array. storedStructure = load('te.mat');
Reference to non-existent field 's'.
Error in Untitled3 (line 7) imageArray = storedStructure.s.I; % Or storedStructure.I depending on what members your structure has.
% Extract out the image from the structure into its own variable. % Don't use I as the variable name - bad for several reasons. imageArray = storedStructure.s.I; % Or storedStructure.I depending on what members your structure has.
% Display the image in a brand new figure window. figure(1); % Display double image, scaled appropriately. % No need to cast to uint8 - could even be bad % if your double numbers don't span the 0-255 range nicely. imshow(imageArray, []);

Just have storedStructure be on its own line after you call load. See what fields it reports to the command window. Then I think you'll see what member to extract. Maybe there is no "s" field and it's called something else, like "I" or "imageArray".

Which one of those fields is an image? Can you do this:
theImage = storedStructure.TestingTargetDataSetC;
imshow(theImage);
