Interpolation


Hi

Is there any kind of interpolation like spline, nearest
neighbor(weighted) that can be used for interpolating a nonuniform data
?

Suppose x = [1 2 4 5 6 8 9 10 12....]
and y=f(x) = [0 -2 4 -3 5 -6....]
and i want to find yy corresponding to xx = [1.8 5.8 9.8..]

How should I proceed? And can somebody please tell me equations used in
spline as applied to this example!!

Thanks
Rose
