When I use:

simOut = sim(MyModel,'SimulationMode','Normal);

to run my simulink model, it appears to be printing the Diagnostics in the command window.

How can I stop this?

It doesn't happen when I run the simulink model directly in simulink, only when I'm using my custom guide GUI.

Thanks!

Or how can I stop state flows from printing to diagnostics? That seems to be the main issue.

I ended up just deleting the Stateflow chart and replacing it with a Matlab function because I could not get the Stateflow to stop printing to diagnostics and the command window despite turning off all the stateflow options in the diagnostics configuration in simulink. I still don't know what was causing it to print.

As per my understanding of your question, I tried the following:

>> vdp
>> simOut = sim(gcs,'SimulationMode','Normal')

Output on command window was:

Simulink.SimulationOutput:
    struct with no fields.
Use get to access a variable by name.
Use getSimulationMetadata to access metadata about the simulation.

If you want to suppress this, just put a semi-colon at the end of "simOut" statement:

>> simOut = sim(gcs,'SimulationMode','Normal');

Sorry yes I forgot the semicolon in my question, but I am already using that.

I think it's the diagnostics printing, but I'm not 100% sure that's just by comparing the output in the command line to the diagnostics viewer.

I don't know what's causing it to print out. Do you have any ideas? I've search for stray missing semi colons but I couldn't see any. Like I said it doesn't print the stuff when I run it directly from simulink so I'm assuming (possibly mistakenly) it's coming from the sim() function?

It's annoying because it prints everything from a stateflow chart (that I don't want to see) so data that I actually do want to look is getting lost.
