FieldUnivariateFunction (Hipparchus 1.4 API)

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:

1.3

- 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.
