# MATLAB Hermite interpolation

Anyone know where I can find the Hermite interpolation algorithm in MATLAB. Which Hermite interpolation algorithm solves this?

I need to calculate a polynomial. Example:

x=[1,2,3];

y=[0.5,1,12]

y'=[1,0.2,0.9]

y''=[0.1,0.6,0.8]

x2=[1,1.5,2,2.5,3,3.5];

polynom=hermit_interpolation(x,y,y',y'',x2); % i need the polynom to

y2=polyval(polynom,x2);

plot(x2,y2);

There is the pchip command documented here.

Note that pchip() is a method for specific variety of cubic Hermite interpolation. I gave a discussion here. – J. M. Dec 28 '11 at 3:41
