CPolynomial:Get

CPolynomial:Exists

CPolynomial:Init

CPolynomial:Get

The Get method returns the coefficient value at a specified index, beginning at index 0.

Syntax

value = CPolynomial:Get( n )

n is the index of the coefficient to retrieve.
value is the numeric value of the coefficient.
On success, the coefficient value is returned.
On failure, 0 is returned.

Remarks

If the value n is not a valid index, for example, n < 0, this method returns 0.

Example

Suppose a CPolynomial assigned to P contains 4 coefficients. This following script fragment returns the value of coefficient 1:

P = CPolynomial:new()	-- create a CPolynomial
P:Set( 0, 5.5)	-- set coef[0]
P:Set( 1, 0.144)	-- set coef[1]
P:Set( 6, -0.15221e-12)	-- set coef[6]
Printf("v = %lg", P:Get(1))	-- result: v = 0.144
