probe

I/O and state data for blocks

Syntax

probe
probe (t)s:b
probe modelName (t)s:b
probe gcb
probe level level-type
p


Description

probe sets the Simulink^® debugger to interactive probe mode. In this mode, the debugger displays the I/O of a selected block. To exit interactive probe mode, enter a debugger command or press the Enter key.

probe (t)s:b displays the I/O of the block whose task index is t, system index is s and block index is b.

probe modelName (t)s:b displays the I/O of the block whose task index is t system index is s and block index is b in the modelName model.

probe gcb displays the I/O of the currently selected block.

probe level level-type sets the verbosity level for probe, trace, and dis. If level-type is io, the debugger displays block I/O. If level-type is all (default), the debugger displays all information for the current state of a block, including inputs and outputs, states, and zero crossings.

p is the short form of the command.

Examples

Display I/O for the currently selected block Out2 in the model vdp using the Simulink debugger.

1. In the MATLAB Command Window, enter:

   sldebug 'vdp'

   The MATLAB command prompt >> changes to the Simulink debugger prompt (sldebug @0): >>.

2. Enter:

   probe gcb

   The MATLAB Command Window displays:

   probe: Data of 0:3 Outport block 'vdp/Out2':
   U1     = [0]
