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.
Note
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:blkIdx
, where
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 tout
and yout
.
The following command creates a plot.
(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
example, use eval('s')
to determine the value of s
rather
than step
the simulation.
