Brilliant! I've been looking for a long time to find a simple m file that can produce coefficients, including the starting and ending points, at any derivative.
AND I DIDN'T EVEN HAVE TO BUY THE Signal Processing TOOLBOX,
Thank You

good

There is a line in the file that does b=inv(A'*A)*h. That can be dangerously inaccurate, and slow. One should never multiply by the inverse. Use b=(A'*A)\h instead.

Can you give an example with an input signal? It would help newbies like me a lot. Much appreciated!
