[Scilab-users] Help to set parameters in an Xcos Diagram

[Clément David]

Hello Cédric,

The max integration time interval can be set using the scs_m.props.tol
vector which is documented [1].

To set a specific parameter values, define a variable in the diagram
context which is used as dt then set it the right value the
scicos_context struct.

For more information on setting variable values, take a look at the
"Optimization of a PID" [2] wiki page.
