Hi,
As per my understanding, you are trying to debug your Simulink model which contains MATLAB function blocks. You are looking for a way to display the values of the variables either by inserting a block in his simulation or by using a command that displays the values in the workspace.
There is a block called ‘Display’ in Simulink’s ‘Sinks’ library. You can add it either via the library browser or by double clicking the Simulink canvas and typing ‘Display’ and choosing the one present under ‘Simulink/Sinks’.
An alternative and a better solution would be to display the signal values directly on the signals (connections) of your Simulink model during the simulation and using ‘Step forward’ button instead of ‘Run’ to see the results of your simulation at each step.

In case you specifically want to debug your MATLAB function blocks you can insert breakpoints in your MATLAB function and use the debugger. For more information on how to do that, use the link below:
