LAGRANGE

 

Type:

Command

Description:

Returns the interpolating polynomial of minimum degree for a set of pairs of values. For two

 

pairs, DROITE will fit a straight line.

Access:

Arithmetic, !ÞPOLY L

Input:

A two × n matrix of the n pairs of values.

Output:

The polynomial that results from the Lagrange interpolation of the data.

Flags:

Exact mode must be set (flag –105 clear).

 

Numeric mode must not be set (flag –3 clear).

 

Radians mode must be set (flag –17 set).

Example:

Find an interpolating polynomial for the data (1,6), (3,7), (4,8), (2,9)

Command:

LAGRANGE([[1,3,4,2][6,7,8,9]])

 

8x3 – 63x2 + 151x – 60
