Question re using fieldnames(obj) vs properties(obj) on Matlab class objects:
In earlier versions of matlab, fieldnames(obj) only worked on struct objects; one had to use properties(obj) to get the names of properties in a Matlab class object. (IIRC, as late as 2015x)
It appears that fieldnames(obj) now works for class objects as well. (this on R2024b*, tho IIRC it worked in 24a as well, possibly earlier)
However, R2025b documentation doesn't mention using fieldnames(...) for class objects, and lists properties(obj) as the function to get class object property names. Is this an undocumented feature that may go away, or is this intended behaviour going forward for fieldnames(...) , and documentation just hasn't kept up?
I note that fieldnames(...) cannot be stepped into with the debugger, so am guessing it must be implemented in underlying Java of mex code.
Also of note is that fieldnames(...) has an optional parameter of '-full' which apparently returns inheritance information on java and com objects (though apparently not on inheritance of Matlab parent/child classes).
