Simulink "While Iterator" subsystem development and debugging

4 views (last 30 days)
Historically, when I need to embed a Newton-Raphson iteration in Simulink, I develop it as a Matlab function, and then embed it in Simulink as a Matlab Function. In this job for this application, I would really like to use the subject "While Iterator" subsystem and build the system equations graphically. But, I am having a real problem debugging it. For instance, I can't figure out how to see the interim results. Any guiadance or help? Thanks.

It can be done by using temp array where u can store values at end Of each iteration

The dataset logging format allows you to log all the iterations of For and While Iterator subsystems
I think the To Workspace block with Timeseries format also does it, but I am not 100% sure, I would need to verify.
