Pcauchy random values that follow a Cauchy Distribution

superclass: Pattern

mean The mean of the distribution (defaults to 0.0)

spread The horizontal dispersion of the random values. The distribution is unbounded.

length number of values produced  (default: inf)

// example

(

var a, c, w;

a = Pcauchy(0.0, 1.0, inf);

c = a.asStream.nextN(500);

w = Window.new("Pcauchy", Rect(10, 10, 540, 800));

// plot the values

c.plot(bounds: Rect(10, 10, 520, 380), discrete: true, parent: w);

// a histogram of the values

c.histo(500).plot(bounds: Rect(10, 410, 520, 380), parent: w);

)

(

var a, c, w;

a = Pcauchy(0.0, 10.0, inf);

c = a.asStream.nextN(500);

w = Window.new("Pbetarand", Rect(10, 10, 540, 800));

// plot the values

c.plot(bounds: Rect(10, 10, 520, 380), discrete: true, parent: w);

// a histogram of the values

c.histo(500).plot(bounds: Rect(10, 410, 520, 380), parent: w);
