Dear matlab user,
I know how to run a simulink model from a script, e.g. 'sim('model_name.slx')'.
I would like to run this model one step at a time so that I can update my controller parameters iteratively. How can I achieve this?
With kind regards,
Luuk Spin

This can be done easily from the Simulink user interface using the Debug controls. Many block parameters are tunable while the model is running or halted in the debug mode. The Simulink Dashboard library also has a number of user interface blocks that can be linked to parameters in your model and changed dynamically while the model is running.

What the other comment recommends, using sldebug, is the programmatic interface for low-level debugging of simulations. Based on what you describe, this might be more than you need. The sldebug interface can require a fair amount of knowledge about the software.
There are also options for stepping simulations one time step at a time on the Debug tab of the toolstrip. The doc currently refers to this as the "Simulation Stepper". It sounds like this would suit your needs and it's much simpler and more interactive. Here's a link to the doc on these features: https://www.mathworks.com/help/simulink/simulation-stepper.html
If you are looking to do this programmatically, there isn't a feature designed for that. While the sldebug interface is a programmatic debugging interface, it isn't supported for scripting. sldebug is meant for an interactive workflow where you enter commands in the Command Window.
