Method Summary

Modifier and Type	Method and Description
public double	Returns: the function value for the given point. value(double[] Point at which the function must be evaluated. point) Compute the value for the function at the given point.

value	back to summary
public double value(double[] point) Compute the value for the function at the given point. Parameters point:double[] Point at which the function must be evaluated. Returns:double the function value for the given point. Exceptions DimensionMismatchException: if the parameter's dimension is wrong for the function being evaluated. MathIllegalArgumentException: when the activated method itself can ascertain that preconditions, specified in the API expressed at the level of the activated method, have been violated. In the vast majority of cases where Commons Math throws this exception, it is the result of argument checking of actual parameters immediately passed to a method.

value

public double value(double[] point)

Compute the value for the function at the given point.

Parameters

Returns:double

the function value for the given point.

Exceptions

DimensionMismatchException:: if the parameter's dimension is wrong for the function being evaluated.
MathIllegalArgumentException:: when the activated method itself can ascertain that preconditions, specified in the API expressed at the level of the activated method, have been violated. In the vast majority of cases where Commons Math throws this exception, it is the result of argument checking of actual parameters immediately passed to a method.
