1.3.1.0

Fixed the error in version 1.3.0.0 pointed out by Jacob Bresler.

1.3.0.0

As requested by Jacob Bresler, I have added optional outputs S and mu, to make the output from polyfix conform with polyfit

1.2.0.0

Fixed trivial errors in the help section

1.1.0.0

Version 1.1 includes an option for specifying derivatives. p is now a row vector, for consistency with polyfit
