CPolynomial:Empty

CPolynomial:Empty

The Empty method deletes all coefficients from the set.

Syntax

CPolynomial:Empty()

Remarks

This resets to zero array elements without deleting the CPolynomial object itself. If you delete the CPolynomial, the object is set to nil and cannot be used again without creating a new instance with new. By calling Empty, the existing CPolynomial can be used to Set new orders, and so forth.

Example

The following script fragment empties the coefficients from CPolynomial P:

P = CPolynomial:new()	-- create a CPolynomial
P:Set( 0, 5.5)	-- set coef[0]
P:Set( 1, 0.144)	-- set coef[1]
P:Set( 4, -1.045e-6)	-- set coef[4]
Printf("Ncoefs = %d", P:Count())	-- result: Ncoefs = 3
P:Empty()	-- empty the CPolynomial object
Printf("Ncoefs = %d", P:Count())	-- result: Ncoefs = 0
P:delete()	-- if finished with P, clean up memory
