Configure simulation debugging session to display information each time algebraic loop is solved
atrace configures the simulation
debugging session to display information each time an algebraic loop is solved in
the 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.
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 information to display
Level of information to display, specified as one of these options:
0— No information
2— Loop variable solution, number of iterations required to solve loop, estimated solution error
3— All information for
2plus the Jacobian matrix used to solve the loop
4— All information for
3plus intermediate solutions for the loop variable
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
stop command, are available for use in the MATLAB Command Window.
