Is it possible to generate a Matlab script from a Simulink model?

Matlab provides a method for programmatically modifying or generating Simulink models ( https://www.mathworks.com/help/simulink/ug/approach-modeling-programmatically.html ).

I have a large collection of Simulink models that I would like to convert into scripts which, when executed, would then re-generate the orginal (or functionally equivalent) model. In effect, I want a way to seemlessly convert between .slx files and a text-based representation. Does Matlab provide a utility that does this?

Hi Hawkeye,

Interesting question.

If you don't mind me asking, what is the use case for such a utility?

[Richard Crozier]

@Paul one use case would be a diffable text representation of the model that would be compatible with Git version control without special programs. I'm interested in the idea myself.

[Paul]

Is the .mdl format still supported? I thought that format was just a text file. Maybe .slx can be converted to or saved as mdl?

@Paul

Indeed, .mdl file format is still supported (as of R2025b.) And that might satisfy the need as expressed by @Richard Crozier . It is not really clear to me, though, whether or not that would satisfy the original request by @Hawkeye

There is no such utility to do this.
