Display solver information in simulation debugging session
strace configures a simulation
debugging session to display information about the solver as you step through a
simulation. Specify the level of information to display using the
lvl input argument.
When you start the simulation debugging session programmatically, the information is displayed in the MATLAB® Command Window.
When you start the simulation debugging session using the Simulink® Editor, the information is displayed in the Diagnostic Viewer.
Displaying solver information in a simulation debugging session can help you determine whether choosing a different solver could improve simulation performance.
You can use this function in a simulation debugging session started:
This function is available only for simulation debugging sessions started programmatically and for interactive simulation debugging sessions while paused within a time step.
lvl — Level of solver information to display
Level of solver information to display, specified as a scalar between
4, inclusive. A higher value
indicates a higher level of information. To stop displaying solver
information in a simulation debugging session, specify the argument as
When you configure a simulation debugging session to display solver information, the software displays several types of timing information related to the solver computations. For information about the notation, use this command.
To start a simulation debugging session interactively, add one or more breakpoints to your model, and in the Breakpoints List, check that Pause within time step is selected. When the simulation pauses on a breakpoint, some of the programmatic debugging commands, such as the
stopcommand, are available for use in the MATLAB Command Window.
