问题
I have a simulation that runs in Simulink with input base on a set of 5000 samples. With my simulation time set to 5000 steps, the model runs (in about 2 seconds) and then I get the results. Is there a way I can change my model so that it runs more slowly and I can see the results change as the simulation progresses? I haven't touched Matlab or Simulink for about 12 years so assume I'm a noob. I'm sure the information is there somewhere in one of the manuals I just don't know what to look for :-(

Yes, there are various utilities to slow down the execution of a Simulink model on the File Exchange. Here are a few:
- Real-Time Pacer for Simulink
- Simulink Real-Time Execution
- Real-Time Blockset 7.1 for Simulink
- Simulink Block for Real Time Execution
- RTsync Blockset

I have a device that I sometimes drive with data from Simulink over a UDP connection. Here's the quick and dirty trick I use to make sure that simulation runs in real time so the device receives data at the correct rate:
Simply dropping in an audio device source and sink forces the model to run at real time because your audio device must. It doesn't have to interact with the rest of your model in any way.
It's not a solution you would use for any sort of final model, but it works great for quick one-off simulations.
These blocks come from the DSP toolkit, although there may be others that provide it too.
