FunctionInterpolation

FunctionInterpolation
evaluates expr with x running from to and constructs an InterpolatingFunction object which represents an approximate function corresponding to the result.
FunctionInterpolation
constructs an InterpolatingFunction object with several arguments.
Computes an InterpolatingFunction representation of Exp[-Sin[x]^2]:
Use the resulting function as any function:
