Anyone know where i find the Hermite interpolation algorithm in MATLAB. Which Hermite interpolation algorithm solve this?
I need to calculate a polynom. Example (just 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);
Thanks for any answers.
The function is
pchip(), which is documented nicely with examples at: http://www.mathworks.com/help/techdoc/ref/pchip.html.
