I have these below codes:

a(1).x = 3;
a(2).x = 1;
a(3).x = -5;
a(4).x = 2;
b = [0 0];
b = a(1:2).x

======================

output => b = 3

I want variable b be equal to [3 1] but variable b is 3.

(Note: "[b(1) b(2)] = a(1:2).x" is not Suitable Answer for me Because for bigger array this solution is overwhelming)

Please Help me.

Thanks

Try

>> b = [a(1:2).x]
b =
     3     1
