Constructor Detail

DistTriangular

public DistTriangular(StreamInterface stream,
                      double min,
                      double mode,
                      double max)

constructs a new triangular distribution with a minimum, mode, and maximum.

Parameters:

stream - StreamInterface; the random number stream

min - double; the minimum

mode - double; the mode

max - double; the maximum

Throws:

IllegalArgumentException - when mode < min or mode > max or min == max

Method Detail

draw

public double draw()
