The value of the function

eval

public double[] eval(double[] input)

An empty but required evaluate method

Specified by:

eval in interface BasicFunction

Parameters:

input - The values used to evaluate the function

Returns:

eval

public double[] eval(double[] input,
                     double time)

The acual evaluate method for this function. The equation implemented here is dq/dt=sum(q_trib)-q ds/dt=P-E-q_surf-q_sub Where q_trib is the flow for the incoming links, s is the storage in the hillslope, P is precipitation, E is evaporation, q_surf is the overland runoff and q_sub is the subsurface runoff

Specified by:

eval in interface BasicFunction

Parameters:

input - The values used to evaluate the function

time - The time at which the function is evaluated

Returns:

The value of the function
