How to select a folder using uigetdir and use folder location later?

After acccessing a particular folder using uigetdir, i want to use folder location later in my code.

In the code mentioned below, how i can get the folder location details in the DOTTED place.

Please help me with that.

Thanks!

directory_name = uigetdir; 
File01 = dir(fullfile(directory_name,'*.png'));

srcFiles02 = dir('F:\Matlab\Images\Constants\*.png');

% Comparision
for i = 1 : image01
       Name01 = strcat(..........,File01(i).name);
           ---

Do NOT use strcat, you should always use fullfile to build filepaths, just like you did for dir. Like this:

aa = fullfile(directory_name, srcFiles(j).name);

and exactly the same for bb:

D = 'F:\Matlab\Images\Symbols_Constants';
srcFiles2 = dir(fullfile(D,'*.png'));
...
    bb = fullfile(D,srcFiles2(j).name);
...

If subfolders are searched, like if he wants to use double star in the file pattern passed to dir(), then D is not a constant and he should use

fullFileName = fullfile(srcFiles2(j).folder, srcFiles2(j).name);
image2 = double(imread(fullFileName));  % Read in the second image

Also, in general using single letter variables instead of descriptive ones leads to an alphabet soup mess of a program that is cryptic and hard to follow. However it's good to see an attempt at adding comments was made.
