SuperCollider CLASSES

Pexprand

random values that follow a Exponential Distribution
Inherits from: Pwhite : Pattern : AbstractFunction : Object

Class Methods

*new (lo: 0.0001, hi: 1, length: inf)

NOTE: lo and hi should both be positive or negative (their range should not cross 0).

Arguments:

lo

lower boundary of values.

hi

upper boundary of values

length

number of values produced.

Examples

(
var a;
a = Pexprand.new(0.0001, 1, inf);
c = a.asStream.nextN(500);
// 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);
)

// sound example
