You can print a block diagram:
Interactively, in the Simulink® Editor, on the Simulation tab, click Print
Programmatically, use the MATLAB®
print command
To control some additional aspects of printing a block diagram,
use the set_param command with model parameters.
You can use set_param with the interactive and
programmatic printing interface.
In addition to printing a model using default settings, you can:
By default, the canvas (background) of the printed model is white. To match the color of the model, set the Simulink Preferences > General > Print preference.
