To get rid of this warning, edit the code and replace "loadimage" with
"imread".

Okay, this part of the code uses a rather annoying Matlab construct.
Basically, you have to remove the exclamation point (!) from the above
code. In line 48 where it says

  eval(command);

you should write

  system (command);

instead.
