Accessing all fields within a struct level at once

If I have a struct A which looks like:

A.('one').('include') ; A.('two').('include'); A.('three').('dont include');

and so on, how can I directly check if 'dont include' is present in the third level of the structure without having to use a loop. Is this possible to achieve without implementing a loop?

[Voss]

'dont include' is not a valid field name, so what does the struct really look like?

Rather than describing the struct, maybe it's better to save it in a .mat-file and upload it here (using the paperclip button).

Hi, I've attached the mat file

"Is this possible to achieve without implementing a loop?"

Not really, but you can hide the loop using STRUCTFUN:

A.one.include = 1;
A.two.include = 2;
A.three.dontinclude = 3;

F = @(s)isfield(s,'dontinclude');
structfun(F,A)

ans = 3×1 logical array
   0
   0
   1

Hi, this is how my mat file looks like in reality

Do you have another question?

Hi Vaishnavi,

I understand that you are trying to find if "dontinclude" is a structure property without using for loops.

One possible solution is to create a function which evaluates every level of structure to check if the property is present.

Here is an example code with the listed recommendation

funcCheck = @(struct)isfield(struct,'dontinclude');
structfun(funcCheck,A)

Returns a "n x 1" logical array, where "n" is the number of levels in the structure.

Hope this helps.
