Best Answer

Since it is p-code, it is (almost) impossible to know why an error occurs. As long as your input is correct, the code should yield the correct output. That is the 'agreement' you have with the developer: they can keep their code secret, you have bug-free code. Since apparently this file is generated on a very old Matlab version, there may very well be compatibility issues. There are two solutions to your problem:
  • use the same Matlab version to run this code as it was compiled on (or at least a very old release)
  • get in touch with the developer of this code and ask them to recompile it with a newer Matlab version
