Sending a floating value from simulink model to workspace

Hi,

I have a simulink model with some output variables and I should use them in a realtime elaboration by m-file algorithms. For example I need to plot in 3d space an output position from model and so create a realtime 3d plotting. Ho can I do it ?

I've tried to use 'To Workspace' block but it doesn't allow to use variable value before simulation end (as realtime using).

Thanks

See Accessing Block Data During Simulation. There is also a great demo that you can start with as an example:

   >> sldemo_msfcn_lms

Start the simulation and double-click on the box where you are instructed to do so. The simulation runs for infinity, and the plot is continuously updated during simulation.

but I don't want an infinity simulation time. Can I apply it for limited time too ?

Yes, you should be able to use for limited time as well.
