Is there a way to get the data types of a structure without manually or programmatically going through each element (and potentially recursively)?

1) Simple case: >> files = dir('*.*'); >> files

27x1 struct array with fields: name date bytes isdir datenum

>> class(files(1).name) ans = char

I can check each field individually but think there ought to be some way of getting the data type side-by-side. I've tried who, whos, fieldnames, and such without success

2) Less simple cases: Since big structs can have little structs within them, I'm trying to figure out how to determine the overall organization of a complicated "as-received"structure. I am currently doing it by looking in the workspace editor and making notes but this has its limits
