Reading many txt files to import some vectors

Dear Users I have question about reading txt files that i attached them if someone could help please. write a program in Matlab that reads output files like the ones above for a number of different ions and makes plots of the transition rates A, the gf values or the S value, as decided by the user, for transitions between selected upper and lower state symmetries along the iso-electronic sequence. The user should be able to specify the names of the files to be read and also give the nuclear charge Z corresponding to each file. The user should be able to specify the file (f1 or f2), the symmetry and the number within the symmetry for the upper state and the file, the symmetry and the number within the symmetry for the lower state. Your program should read data in all files and identify if the given transition is present in all data files. If the specified transition is present in all data files your program should plot the transition as a function of Z. If the specified transition is not present in all data files your program should notify the user asking him to supply new symmetries and levels.

I did the following script as filename_txt = 'transition'; lines = {}; line_num = 0; index=0; all_arrays = {}; array_size = 0; first_file=22;last_file=24;

for k=22:24 filename = [filename_txt,num2str(k),'.txt']; d = fopen(filename, 'r'); if (d < 0) fprintf('file %s does not exit\n', filename); continue; end %reading the lines from first to dash2 and do nothing for them tline = fgets(d);

    while ischar(tline)

      tline=fgets(d);

      if (strncmpi(tline, ' f', 2) || strncmpi(tline, '      ', 6))
        split = regexp(tline, '\s+', 'split');
        if (length(split) > 5)
            line_num = line_num + 1;
            lines{line_num} = split;
        end
      end
    end
    disp(lines);
    fclose(d);
end

My problem when i run it i got the following message ??? Operands to the and && operators must be convertible to logical scalar values.

Error in ==> try2 at 213 if (user_f2==f2 && user_J1 == j_1 && user_parity1 == parity_1 && user_lev1==lev_1 && user_J2 == j_2 && user_f1==f1 && user_parity2 == parity_2 && user_lev2==lev_2 ) Any one can help please as soon.

Chances are some of those things are not single values, but arrays. Hover the mouse over them and find out which variables are not single scalar numbers.
