MATLAB: How to use Simulink’s “Arrange” options programmatically

alignarrangedistributesimulink

Simulink has many useful functions in the context menu for arranging blocks in a model, as shown in the image below. Is it possible to use these functions programmatically instead of via the context menu? Where can I find the API for these functions?

I am not aware of ways to align or distribute blocks programmatically but, starting Matlab 2018b you can use Simulink.BlockDiagram.arrangeSystem(system) from your MATLAB command window to automatically arrange your model.

Please see the section titled Arrange Model Layouts Automatically in this help document.

AFAIK, there no specific command for Ctrk+K (Referesh model block). But, library block can also be refreshed using update diagram (ctrl+D). Update diagram can be issued using command

>> set_param('YourModel','SimulationCommand','update');

Just for information, in newer version of simulink, library block and model reference block refreshes automatically. See this blog.

MATLAB: How to get the old shorctus back in Simulink 8.0 (R2012b)

Currently, there is no option to return to the old ‘r’ and ‘v’ shortcuts to zoom in and out in Simulink 8.0 (R2012b).

As a workaround, there is an option in Simulink to change the mouse scroll control. To change this setting, please navigate in your model to ‘File’ -> ‘Simulink Preferences’ ->Edit Defaults’ -> ‘Scroll wheel controls zooming’. This box can be checked or unchecked, resulting in two scenarios:

Checked:

Model Scrolling is controlled by holding the Ctrl key and scrolling the mouse wheel. Model zooming is controlled by just scrolling the mouse wheel.

Unchecked (i.e. pre R2012b behavior):

Model Scrolling is controlled by just scrolling the mouse wheel. Model zooming is controlled by holding the Ctrl key and hitting + or – on the keyboard.

On a MAC machine, the Ctrl key would be replaced by the Apple Command key.
