Sometimes we want to fit a polynomial to some data, but want to force a perfect match to some known values at one or more points. This function returns such a polynomial.

Added image
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
