Constructor Detail

Sim_gamma_obj

public Sim_gamma_obj(String name,
                     double scale,
                     double shape)
Constructor with which Sim_system is allowed to set the random number generator's seed

Parameters:
name - The name to be associated with this instance
scale - The scale of the distribution
shape - The shape of the distribution

Sim_gamma_obj

public Sim_gamma_obj(String name,
                     double scale,
                     double shape,
                     long seed)
The constructor with which a specific seed is set for the random number generator

Parameters:
name - The name to be associated with this instance
scale - The scale of the distribution
shape - The shape of the distribution
seed - The initial seed for the generator, two instances with the same seed will generate the same sequence of numbers
