Did you notice that in R2015a, simulations now have metadata in their output?<\/p>\r\n\r\n

What is simulation metadata?<\/strong><\/p>\r\n\r\n

The getSimulationMetadata<\/a><\/tt> method of the Simulink.SimulationOutput<\/a><\/tt> object returns a Simulink.SimulationMetadata<\/a><\/tt> object. It has four properties:\u00a0ModelInfo<\/tt>,\u00a0TimingInfo<\/tt>,\u00a0UserString<\/tt>, <\/strong>and UserData<\/tt>.<\/strong> ModelInfo<\/tt><\/strong> contains some basic information about the model and solver.<\/p>\r\n\r\n

\"Model<\/p>\r\n\r\n

Timing information<\/strong><\/p>\r\n\r\n

No more need to insert tic<\/tt><\/a> and toc<\/tt><\/a> calls in your model callbacks<\/a>. The TimingInfo<\/strong><\/tt> field of the metadata informs you of the time it took for your model to initialize, execute, and terminate:<\/p>\r\n\r\n

\"Model<\/p>\r\n\r\n

Custom information<\/strong><\/p>\r\n\r\n

If you want to add notes or relevant data, you can use the UserString<\/tt><\/strong> and UserData<\/tt><\/strong> properties. They\u00a0can be set using their respective methods of the parent Simulink.SimulationOutput<\/a><\/tt> object: setUserString<\/a><\/tt> and setUserData<\/a><\/tt>.<\/p>\r\n\r\n

\"Model<\/p>\r\n\r\n

Now it's your turn<\/strong><\/p>\r\n\r\n

What are you going to store in the Simulink.SimulatuonOutput UserData<\/tt><\/strong> field? Let us know by leaving a comment here<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
