Interface FieldUnivariateFunction

All Known Implementing Classes:

PolynomialFunction, PolynomialFunctionNewtonForm, PolynomialSplineFunction

public interface FieldUnivariateFunction

An interface representing a univariate real function for any field type.

This interface is more general than RealFieldUnivariateFunction because the same instance can accept any field type, not just one.

Since:

Method Summary

Modifier and Type	Method	Description
default <T extends RealFieldElement<T>> RealFieldUnivariateFunction<T>	toRealFieldUnivariateFunction(Field<T> field)	Convert to a RealFieldUnivariateFunction with a specific type.

Method Detail

toRealFieldUnivariateFunction

default <T extends RealFieldElement<T>> RealFieldUnivariateFunction<T> toRealFieldUnivariateFunction(Field<T> field)

Convert to a RealFieldUnivariateFunction with a specific type.

Type Parameters:

T - the type of the field elements

Parameters:

field - field for the argument and value

Returns:

converted function

value

<T extends RealFieldElement<T>> T value(T x)

Compute the value of the function.

Type Parameters:

T - the type of the field elements

Parameters:

x - Point at which the function value should be computed.

Returns:

the value of the function.

Throws:

IllegalArgumentException - when the activated method itself can ascertain that a precondition, specified in the API expressed at the level of the activated method, has been violated. When Hipparchus throws an IllegalArgumentException, it is usually the consequence of checking the actual parameters passed to the method.
