Hello
I would like to run a batch of simulation using matlab/simulink. The problem is, for every calculation Matlab/simulink is closed and reopened. This takes an eternity, especially considering the simulation only runs for 10-20sek but startup takes up to 1min!!!!
I'm considering to use Matlab via COM-Server. meaning it stays alive during my runs and its administrated from an extra program which selects the relevant Model/Data and runs a simulation.
Now the questions:
  • Is it possible to have more then one Matlab COM Server running in parallel
  • Is there another way to dramatic reduce startup time (<< 10s!)
  • has somebody else tried something like this
... administrating the simulation from inside Matlab is currently not an option
Thanks for any comments/ideas

Hi Nobert,
There are much better ways to run batch simulations:
1. Use parallel computing toolbox to make use of all the cores on your machine or a pool

2. If you want to change the parameter values of the same model and do Monte Carlo Simulations,

3. Use Batch job in Simulink Projects

Hope this helps
