I want to set path where to save a file. But this saving function is in loop and name of saving variable is changing every iteration.
for k....
  for l......
 filename = [ 'delta',num2str(l) ,num2str(k), '.mat'];
  save(filename,'delta')
  end 
end

filepath=['c:\....\' int2str(l) '\'];
Thanks for help!!
