MATLAB: Speed up simulation

Question

Hello,

I've read some of the questions posted on mathworks regarding this subject, but still I want to speed up the simulation for example by 10 times or 100 times.

The reason to do this is because I'm using a signal builder with lots of values used for testing a model and writing the outputs in an excel and to do this for all the values would take about 7h…

Thanks in advance, Alex

There are several techniques for improving your Simulink model's performance. Please see these articles:

• Tips for Simulation Performance
• Speeding Up the Simulation
• Simulink Performance & Memory Management Guide

Also, you mentioned writing outputs to an Excel file - do you do this at the end of simulation or at each time step? I'm assuming you use the XLSWRITE command?
