Debug Simulations Programmatically - MATLAB & Simulink (original) (raw)
Main Content
Debug and analyze simulations in the MATLAB® Command Window, set breakpoints, step through time steps and block methods
The Simulink® debugging programmatic interface provides debugging options in the MATLAB Command Window that are similar to those available in the Simulink Editor. In addition, you can use the programmatic interface to:
- Step through model execution one block method at a time.
- Set breakpoints on block methods.
- Set additional model breakpoints, such as the solver reset breakpoint.
- Display additional information about the model, including a list of nonvirtual subsystems.
The functions for controlling data display and model execution in a simulation debugging session are available only after you start the debugging session.
