Student[NumericalAnalysis][Draw] - create a plot of a certain aspect of an interpolation structure

Calling Sequence

Draw(p, opts)

Parameters

p

-

a POLYINTERP structure

opts

-

(optional) equation(s) of the form keyword=value where keyword is objects; objects to plot

Description

• 

The Draw command plots different components of an interpolation structure.

• 

By default, the Draw command plots the following objects: the data points, the approximate polynomial, the function, and the extrapolated points, as long as they are available.

• 

If the option objects is provided, the Draw command will plot the specified objects.

• 

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

• 

The colors of each object in the plot can be specified using the SetColors mechanism.

Examples

xy:=0,1,12,1,1,1110,32,34,2,78,52,910,3,1110,72,1

xy:=0,1,12,1,1,1110,32,34,2,78,52,910,3,1110,72,1
