scicosim(Janvier 1997) scicosim(Janvier 1997)
NAME
scicosim - Scicos simulation function
CALLING SEQUENCE
[state,t]=scicosim(state,0,tf,sim,'start' [,tol])
[state,t]=scicosim(state,tcur,tf,sim,'run' [,tol])
[state,t]=scicosim(state,tcur,tf,sim,'finish' [,tol])
PARAMETERS
state : Scilab tlist contains scicosim initial state. Usually gen-
erated by Scicos Compile or Run menus (see scicos_cpr for more
details).
tcur : initial simulation time
tf : final simulation time (Unused with options 'start' and 'fin-
ish'
sim : Scilab tlist. Usually generated by Scicos Compile menu (see
scicos_cpr for more details).
tol : 4 vector [atol,rtol,ttol,deltat] where atol, rtol are respec-
tively the absolute and relative tolerances for ode solver (see
ode), ttol is the precision on event dates. deltat is maximum
integration interval for each call to ode solver.
t : final reached time
DESCRIPTION
Simulator for Scicos compiled diagram. Usually scicosim is called by scicos
to perform simulation of a diagram.
But scicosim may also be called outside Scicos. Typical usage in such a
case may be:
1 Use Scicos to define a block diagram, compile it.
2 Save the compiled diagram using Save,SaveAs Scicos menus .
3 In Scilab, load saved file using load function. You get variables
scicos_ver, scs_m, cpr
scs_m is the diagram Scicos main data structure.
cpr is the data structure list(state,sim,cor,corinv) if the diagram had
been compiled before saved, else cpr=list()
4 Extract state, sim out of cpr
5 Execute [state,t]=scicosim(state,0,tf,sim,'start' [,tolerances]) for
initialisation.
6 Execute [state,t]=scicosim(state,0,tf,sim,'run' [,tolerances]) for
simulation from 0 to tf. Many successives such calls may be performed
changing initial and final time.
7 Execute [state,t]=scicosim(state,0,tf,sim,'finish' [,tolerances]) at
the very end of the simulation to close files,...
For advanced user it is possible to "manually" change some parameters
or state values
