Pcauchy random values that follow a Cauchy Distribution


superclass: Pattern



Pcauchy(mean, spread, length)

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);

)
