The RSim target was designed to let you run batch simulations at the fastest possible speed. Using variable-step or fixed-step solvers with RSim combined with the use of a tunable parameter data structure, whether you set Default parameter behavior to
Tunable or to
Inlined, you can create multiple parameter sets to run with the RSim target's standalone executable file (.exe on Windows) generated using Simulink Coder. Each invocation of the executable allows specification of the file name to use for results.
For this example, Default parameter behavior is set to
Inlined. The model declares workspace variables as tunable parameters. To use RSim with Default parameter behavior set to
Tunable, and without explicitly declaring tunable parameters, see Use RSim Target for Batch Simulations.
Open the example model
This model uses the RSim target and the
rsimgetrtp function to allow a non real time executable to be passed new data without the need to recompile the Simulink model. This feature allows you to get a map of the tunable parameters declared in a model and save it in a MAT-file. You can then create your own MATLAB GUI or a standalone GUI (independent of MATLAB) to read and write the MAT-file and rerun the executable to produce new output files.
Double-click the buttons at the upper right sequentially to run the example.
To review the code used to create both the MATLAB GUI and standalone GUI, double-click the View MATLAB programs button.
