Convert char fields of structure into a cell array

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?

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 {}.

Jesus! Thanks. You don't know how much frustrated I was trying to get this working. What a nightmare!

Isn't there any good manual where explains differences between arrays, cells and structs? The use of [], (), and {} can be sometimes misleading.

Hi Dani,

For cell arrays, probably this:

The higher level page that leads to pages like the above would be this one:

Hey thanks! I've been looking for a solution like this as well.

Hi, I tried it and got a new string vector :) super , but do you know how to change it directly in the Structure (A here) ? Thanks

I think what u need is B = char(A.a)
