artest(1) Scilab Function artest(1)
NAME
lotest - demo of the Lorenz attractor
CALLING SEQUENCE
[]=lotest([f_l,odem,xdim,npts,pinit])
[y]=lorenz(t,x)
[]=ilo(sig,ro,beta)
[]=ilof(sig,ro,beta)
PARAMETERS
f_l : can be "loren" or lorenz. it is the name of the external for the
Lorenz system. "loren" will use a Fortran coded version of the lorenz
system and arnold will and loren will use a Scilab coded
version.lorentz is the Scilab macro which code the lorenz system.
This macro is loaded when calling lotest.
ilof, ilo
:are used to fix the parameters of the Fortran and Scilab code version
of the Lorenz system.
odem,xdim,npts
: are optional arguments. Their meaning and syntax can be found in the

DESCRIPTION
A call to the function lotest() will interactively display a phase portrait
of a the following dynamical system
y(1)=sig*(x(2)-x(1));
y(2)=ro*x(1) -x(2)-x(1)*x(3);
y(3)=-beta*x(3)+x(1)*x(2);
