MATLAB: Are non-scalar signals not displayed with wide lines in Simulink 7.4 (R2009b)

simulink

When I create a new model from scratch, all signals including non-scalar ones are displayed as thin lines.

Best Answer

In order for non-scalar signals to be displayed with wide lines, make sure that the following menu option is set:
Format -> Port/Signal Displays -> Wide Non-scalar Lines
After setting this option, you can click on Edit -> Update Diagram (Ctrl+D) in order for the signal lines to get updated.
To make this option default for new models, set the following option:
File -> Preferences -> Simulink Preferences -> Display Defaults ->Wide non-scalar lines
