Method Detail

eval

default double eval(VectorNd in)

Evaluates this function for the specified inputs. The input vector size must the value returned by FunctionNx1.inputSize().

Specified by:

eval in interface Function3x1

Specified by:

eval in interface FunctionNx1

Returns:

function output value

eval

double eval(Vector3d deriv,
            Vector3d in)

Evaluates this function for the specified inputs. If deriv is not null, the derivative is also computed and returned in this argument.

Parameters:

deriv - if not null, returns the derivative values

in - function input values

Returns:

function output value

eval

default double eval(VectorNd deriv,
                    VectorNd in)
