In command-line mode, you control the debugger by entering commands at the debugger
command line in the MATLAB® Command Window. To enter commands at the debugger command line, you must start
the debugger programmatically and not through the GUI. Use
sldebug for this purpose. The debugger accepts abbreviations for debugger
commands. For more information on debugger commands, see Simulink Debugger.
You can repeat some commands by entering an empty command (i.e., by pressing the Enter key) at the command line.
Some of the Simulink® software commands and messages use method IDs to refer to methods. A method ID is an integer assigned to a method the first time the method is invoked. The debugger assigns method IDs sequentially, starting with 0.
Some of the debugger commands and messages use block IDs to refer to blocks. Block IDs
are assigned to blocks while generating the model's sorted lists during the compilation
phase of the simulation. A block ID has the form
sysIdx is an integer identifying the system that contains the block
(either the root system or a nonvirtual subsystem) and
blkIdx is the
position of the block in the system's sorted list. For example, the block ID
0:1 refers to the first block in the model's root system. The
slist command shows the block ID for each debugged block in the model.
You can enter any MATLAB expression at the
sldebug prompt. For example, suppose you
are at a breakpoint and you are logging time and output of your model as
yout. The following command creates a
(sldebug ...) plot(tout, yout)
You cannot display the value of a workspace variable whose name is partially or entirely
the same as that of a debugger command by entering it at the debugger command prompt. You
can, however, use the
eval command to work around this problem. For
eval('s') to determine the value of
step the simulation.
