Subscript indices must either be real positive integers or logicals???

Hi,

Lately I'm getting this error with the following code, which was running well many times. The code stops on the second 'if', which compares the strings.

I've already checked on debugging mode if there's something wrong with the variables, but everything is ok...do you know how it could be possible? I've already restarted Matlab, but the result doesn't change. The Matlab version is R2010a.

Thank you so much!

filenames  = './patch1.mat ./patch2.mat ./patch3.mat';

function Patches = ReadPatches(filenames);

if numel(filenames) > 0;
   spaces  = [0 findstr(filenames, ' ') length(filenames)+1];
   for i = 1:length(spaces) - 1;
      filename                   = filenames(spaces(i)+1:spaces(i+1)-1);
      if filename(end-3:end) == '.msh'
         [c, v]                  = msh2coords(filename);
      elseif filename(end-3:end) == '.mat'  
         load(filename, 'c', 'v')
      end
   end
end

You should be using strcmp() to compare strings, not "=="

At the command line give the command

dbstop if error

and run until the problem occurs. When it does, please show length(filename)

Thank you Walter! I have solved the problem thanks to the command suggested by you (it was a very silly mistake on variable 'filenames'...).

I'll keep it in mind!
