CPolynomial:new

The new method creates an instance of the CPolynomial class.

Note: This method's name uses all lower case to present it as the analog of the C++ new operator. Generally, the names of class methods begin with an uppercase letter but new and delete are different.

Syntax

P = CPolynomial:new()

Default constructor. The new CPolynomial P has no elements.

P = CPolynomial:new( CPolynomial2 )

This is a copy constructor. The new CPolynomial P is initialized to the members of the CPolynomial2 argument.

Example

The following example shows the default constructor and destructor pair:

P = CPolynomial:new()	-- create a new instance of P of the CPolynomial class.
...	-- other uses of the class go here, between new and delete.
P:delete()	-- deletes the object and its associated memory.

The next example shows the use of all 3 constructors: default, copy, and initialization:

P1 = CPolynomial:new()	-- default constructor
P1.Set(3, 4.4)	-- set only coef[3]
P2 = CPolynomial:new(P1)	-- copy constructor
P2:Set(2, 2.0)	-- set Coef[2]
Printf("N = %d", P2:Count())	-- result: N = 2
