Is it possible to access all nested structures in symmetrical struct tree?

I have a struct looking something like this:

struct.nested1.data
struct.nested2.data
struct.nested3.data

Is there a way to access all .data nested structures? Similar to how in UNIX you can do something like

ls folder/*/subfolder

to list the contents of all subfolders.

Hi @Jostein Holmgren,

You can use ‘structfun’ for this purpose. It applies a function to each field in a scalar structure. For example, the ‘data’ members to an example nested structure ‘struct’ can be listed out as follows:

struct.nested1.data = 'a';
struct.nested2.data = 'b';
struct.nested3.data = 'c';
structfun(@(x) disp(x.data), struct);

a
b
c

For more details on the various ways to use ‘structfun’, you can refer to the documentation by running the following command in the MATLAB Command Window:

doc structfun

Hope this helps!
