I would use listdlg:
r = double('AZ'); % Create Data
names = char(randi(r, 10,5));
grades = randi([70 99], 10,1);
the_list = {cat(2, names, repmat(' ', 10, 1), num2str(grades))}; % Create Data
[student_nr, sel] = listdlg('PromptString','Class Results','ListString',the_list);
This allows you to select a particular student, or not, as you wish.
