How can I loop through different input text files when running a .exe in Matlab?

Hello,

I am running a .exe file in Matlab and looping through different input arguments. This is what the code looks like:

for a = [36, 37, 38]

        system(sprintf('spei.exe %d fallon_input.txt %d.txt', a, a));

end

The first argument is a time scale in months. The second argument is the input file. The input file is fallon_input.txt. And the third argument is the output file. My question is how can I loop through different input files for each set of 'a' values?

Just generalize what you have.

textfiles = {'fallon', 'jumpon', 'hopon'};

for a = [36,37,38]
  for K = 1 : length(textfiles)
    system(sprintf('spei.exe %d %s_input.txt %s_output_%d.txt', a, textfiles{K}, textfiles{K}, a));
  end
end

Thanks Walter, this worked great!
