There is no built-in way to do this in MATLAB, and it strikes me as quite difficult to do in a way that is general enough to manage any workspace.
I think the rough outline of how to do this would be
- use the who command to identify the variables in the workspace
- make a structure with fields for each variable
- encode the structure into JSON with jsonencode
One challenge here is the data types that might need to be converted somehow to fit in the MATLAB structure. Things that come to mind are anonymous function handles and MATLAB objects.
All in all, it seems like a daunting task. What are you trying to do with the JSON object that you create? I wonder if you might be falling into the XY Problem.
