MATLAB: Convert char fields of structure into a cell array

Question

I have a structure with fields like

A(1).a='A01'
A(2).a='A02'
A(3).a='A03'

Now I would like to convert this structure into a cell array. I tried with

B=[A.a]
B =
A01A02A03

That is not, what I need. I would like to have:

B = 
      'A01'
      'A02'
      'A03'

Is there an easy way, or do I need to write a loop for that?

Answer 1

You could also use comma-separted list expansion:

ac = {A(:).a}

Similar to what you did above, but rather than concatenating the strings with [], concatenate them into cells with {}.
