Hi all,

I am logging 3 different signals on a Simulink scope and logging the data to the workspace by saving it as a Struct with Time. The struct has another struct within it called 'signals'. The signal struct has a data type called 'values' that I am not familiar with that looks like this.

Can someone please explain this data structure and how I access each of the 3 vectors within it individually.

Thanks!

What shows up for class() of the values field? I suspect it is cell array.

在 MATLAB Online 中打开

It appears from https://www.mathworks.com/help/sldrt/ug/plot-signal-data-logged-to-workspace.html that you probably have a non-scalar struct. Try looking at

   first_signal = ScopeData.signals(1).values;
   second_signal = ScopeData.signals(2).values;
   third_signal = ScopeData.signals(3).values;
