Define a Function from a List in Maple

[penguin007]

Hi,

I've just ploted a graph in Maple from a list thanks to the function pointplot(...,style=LINE). The graph(cf attachment) "looks like" a continuous function. So my question is the following:
Is it possible to define a function from a list in Maple (provided that the plot of this list seems continuous); I mean, I would like to get the value for any abscissa.

Thanks for your help.

A function can be defined from a set of discretely sampled points using an interpolation method. For example, using linear/bilinear/hermite/cosine interpolation or something more advanced like cubic spline or Legendre. Maple does have a Spline function for this
