# FunctionInterpolation

FunctionInterpolation[expr,{x,xmin,xmax}]

evaluates expr with x running from xmin to xmax 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]:

Use the resulting function as any function:

## Scope(1)

Use derivatives to improve the smoothness of the approximation:
