[Scilab-users] xcos : xcos_simulate(scs_m, 1) or xcos_simulate(scs_m, 4)

Hello Quentin,

Both scicos_simulate and xcos_simulate will be supported in the future.
Note that the main difference are:

 * xcos_simulate invoke pre / post simulation hook ; it is called when
the user click on simulation "Start"
 * scicos_simulate can re-use the Info and update context. It bypass
more compilation / simulation steps depending on the arguments value.

Well, both approach fill a specific need. With a setup script it is
slightly easier to edit execute and test using scinotes. Using the
diagram context all the information are contained inside the ZCOS file ;
you can easily mail it.

Let's say : for more than 10 variables or if it contains Scilab function
calls the setup script is much more manageable.
