Polyfit

A Matlab function for deriving how well polly fits.

In the case of a bad approximation, the function will return polyshit.

In the case of an accurate approximation, Polly will be found with a beard on a unicycle drinking a beer.

x = (0: 0.1: 2.5)';
y = erf(x);

p = polyfit(x,y,6)

p =

polyshit
