interpolation of unevenly sampled points


Hi,

I can't seem to get anything from MathSource, so I'll try this group.  


All I need is a way to resample a set of  numbers at specific  
intervals.  Each x has a corresponding y, but the x's are not evenly  
spaced.  I'd like to space them evenly (so I can plot a surface using  
Mathematica), using some simple interpolation algorithm.  I'd write a  
routine myself, but the problems sounds so common I thought someone  
may already have written it.  However, nothing this simple appears to  
exist on the Mathematica archive server.

Does anyone outhere have a "package" that will do this?
