A 3-dimensional numeric vector indicating the starting point for the time series.
Default: c(-13, -14, 47).
time
The temporal interval at which the system will be generated. Default: time=seq(0,50,by = 0.01).
do.plot
Logical value. If TRUE (default value), a plot of the generated Lorenz system is shown.
Details
The Lorenz system is a system of ordinary differential equations defined as:
dx/dt = sigma*( y - x )
dy/dt = rho*x - y - xz
dz/dt = -beta*z + xy
The default selection for the system parameters (sigma=10, rho=28, beta=8/3) is known to
produce a deterministic chaotic time series.
Value
A list with four vectors named time, x, y and z containing the time, the x-components, the
y-components and the z-components of the Lorenz system, respectively.
Note
Some initial values may lead to an unstable system that will tend to infinity.
