Parameter handling for even polynomials.
A 1-dimensional EvenPolynomial's parameters.
An EvenPolynomial
is described by a set of coefficients; its fundamental operation is evaluating itself at some "x". The number of coefficients is the order of the polynomial divided by two, plus one.
Since the EvenPolynomial
is a Function
, the derivatives can be obtained as well.
The parameter interface (see FunctionParam class), is used to provide an interface to the Fitting classes.
This class is in general used implicitly by the EvenPolynomial
class only.
