Apply "whos" to fields of a struct to get their sizes?

The command "whos" shows the sizes (in bytes) [of the data objects/variables in the base workspace. Is there a way to get that information for the fields of a struct?

Something like this, perhaps?

a=rand(100); b=1:4;
S.a=a; S.b=b;

Sbytes=whosstruct(S);

whos a b

  Name        Size             Bytes  Class     Attributes

  a         100x100            80000  double              
  b           1x4                 32  double              

Sbytes

Sbytes = struct with fields:
    a: 80000
    b: 32

function Sbytes=whosstruct(S)

   for fld=fieldnames(S)'
      val=S.(fld{1});
      tmp=whos('val');
      Sbytes.(fld{1})=tmp.bytes;
   end

end

Yes! Exactly! Thanks!

I put it in my MATLAB folder (where all utility functions reside), referring to it as StrucFldBytes.
