Detailed Description

template<class T>
class casacore::PowerLogarithmicPolynomialParam< T >

Parameter handling for one-dimensional power logarithmic polynomials

Review Status

Test programs:
tPowerLogarithmicPolynomial

Prerequisite

Etymology

A 1-dimensional power logaritmic olynomial's parameters.

Synopsis

A power logarithmic polynomial is described by a set of coefficients; its fundamental operation is evaluating itself at some "x".

Since the power logarithmic olynomial 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 PowerLogarithmicPolynomial class only.

Example

Template Type Argument Requirements (T)

  • T should have standard numerical operators. Current implementation only tested for real types (and their AutoDiffs).

Thrown Exceptions

  • Assertion in debug mode if attempt is made to address incorrect coefficients
