MATLAB: Compare .txt to a string.

Question

How can you compare each line of a .txt file to a string?

Answer 1

you can use the function strcmp(). which will compare two strings.

to expand a bit more you can look up the function fgetl() which has the example

          fid=fopen('fgetl.m');
          while 1
              tline = fgetl(fid);
              if ~ischar(tline), break, end
              disp(tline)
          end
          fclose(fid);

and then using strcmp() you'd insert in the for-loop

 same = strcmp(tline,'comparisonstrings');

i'll leave it to you to figure out how you want to save/store the results.
