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.
