Zoom and center Simulink model program (alt+1 & spacebar)

Trying to program the same functionality as you see in the "alt+1" and "spacebar" shortcuts into a callback function that will run when you open a model. The best I have found is the Simulink.scrollToVisible function but that doesn't seem to always zoom to 100% and center the models.

Hi Richard,

There's a 'Fit to View' option in the Explorer Bar(the bar that appears on the left hand side of the Simulink model). It essentially performs the same function as 'alt+1' and 'Spacebar' shortcuts.

Yea, I saw that but that doesn't actually help me. I need to program this into a starting script for when open a model

Hi Richard,

You can set the Simulink window's view using the system's 'Zoomfactor' parameter. For example:

set_param(gcs,'Zoomfactor','fit to view')

will zoom and centre the current Simulink system as the spacebar does.

[Simon Greenwold]

You can either fit the entire system with

set_param(gcs, 'ZoomFactor','FitSystem')

or just what's currently selected with

set_param(gcs, 'ZoomFactor','FitSelection')
