%use Compare strings
strcmp(T(:,1),string(label))
%or Compare strings (case insensitive)
strcmpi(T(:,1),string(label))
Check this: strcmpi or strcmp

% comparion of the found image with the student database
if(strcmpi(T(:,1),string(label)))
disp(strcat('Student=',string(label)));
disp('Found');
col={'ID','Attendance'};
dat={string(label),'P'};
unitable('columnname',col,'Data',dat);
end
it doesnt disp the statements under the if condition and directly goes to the next condition
