# How to create a function in matlab given the y values?

I was wondering if it is possible to create a function f(x) in matlab based on y values.

Example X=[0,1,2,3,4,5,6,7,8,9] Y=[5,6,7,8,9,10,11,12,13,14]

In this trivial example I wish to get f(x)=x+5

If my memory serves me well, I remember that maple provide such capability. Wonder if this can be done in matlab?

Thanks

You'll want to look into polyfit() and polyval(). – J. M. Oct 6 '11 at 14:17
(If you're just trying to find a fit for some data, not necessarily in Matlab, try zunzun.com/FunctionFinder/2 ) – endolith Oct 7 '11 at 14:19
