How to get a list of the structures used in a matlab code?

I need to get familiar with a large MATLAB code somebody else created. I would like to create a list of all the structures for documentation purposes. Any ideas?

Thanks

This can be a bit difficult to define. Technically, MATLAB considers each different struct to be a different data type. For some purposes, two structs are considered to be compatible if they have the same field names; for other purposes two structs are considered to be compatible only if they have all the same field names in the same order.

If you got a "large code" (maybe some 100'000 lines of code) and it is not well documented, you are in pain. Such "brownfield projects" are extremely hard to debug, because you have to guess the purpose of the code. Therefore it is usually more efficient to delete the code and rewrite it.

But let's assume that this is not an option. Then getting a list of structs can be done only by reading the source code and collect, where which struct is defined and how. There is no magic tool to do this. Maybe the debugger helps you: Set a breakpoint at the end of each function and get the contents of the currently existing structs:

S = whos;
S = S(strcmp({S.class}, 'struct'));
disp(S)

Thanks, but all I wanted is the list of the names of the objects shown in the workspace. Isn't a simple way to get this?

@Robert: Please post comments in the section for comments to avoid unnecessary confusion. Thanks.

Uhm. Yes. Use the code I've posted.
