FunctionInterpolation[expr, {x, xmin, xmax}]
evaluates expr with x running from 
to 
and constructs an InterpolatingFunction object which represents an approximate function corresponding to the result.
FunctionInterpolation[expr, {x, xmin, xmax}, {y, ymin, ymax}, ...]
constructs an InterpolatingFunction object with several arguments.

Basic Examples (1)
Computes an InterpolatingFunction representation of Exp[-Sin[x]^2]:
| In[1]:= |
| Out[1]= |  |
Use the resulting function as any function:
| In[2]:= |
| Out[2]= |  |
