Student[NumericalAnalysis][DataPoints] - return the data points from a POLYINTERP structure

Calling Sequence

DataPoints(p)

Parameters

p

-

a POLYINTERP structure

Description

• 

The DataPoints command retrieves the interpolated data points from a POLYINTERP structure.

• 

The POLYINTERP structure is created using the PolynomialInterpolation command or the CubicSpline command.

Examples
