You need to specify the path that you gathered with 'test_image', otherwise the dir command is just going to search the current directory.

test_image = uigetdir('F:\R Project\');
mat = dir([test_image,'\*.jpg']);

What is the error message you're getting?

[OriAlpha]

Cannot open file "." for reading. You might not have read permission.

Error in imread (line 340)

fullname = get_full_filename(filename);

Error in sample (line 11)

im = imread(test_image1);

It seems that the mat file isn't gathering the correct file name, so it is unable to load. I would suggest doing some more robust debugging of your own. Check things like making sure you don't have double slashes in your directory name, or aren't missing a slash. Try copying the name directly from file explorer and loading it directly, rather than having matlab generate the name reactively.
