Rossler chaotic generator

Description

A strange attractor discovered by Otto Rossler based on work in chemical kinetics. The system is composed of three ordinary differential equations:

x' = - y - z y' = x + ay z' = b + z(x - c)

The time step amounthdetermines the rate at which the ODE is evaluated. Higher values will increase the rate, but cause more instability. A safe choice is the default amount of 0.05.

Examples

These first examples treat RosslerL as a single-output UGen (i.e. using x only):
