Check Signal Attributes
5-57
Note that when Signal dimensions is selected from the model window
Format menu, Simulink displays the size of a 1-D vector signal as an
unbracketed integer, and displays the dimension of a 2-D signal as a pair of
bracketed integers,
[MxN]. Simulink does not display any size information for
a 1-D or 2-D scalar signal. Dimension information for a signal can also be
displayed in a model by attaching a Probe block with
Probe signal
dimensions
selected.
