How do I combine a structure array into one structure

I have a structure array where each field of the same name is the same size. I want to combine each field over the array into one field. For example:

A(1).x = [1 2 3];
A(1).y = [4 5 6];
A(2).x = [7 8 9];
A(2).y = [10 11 12];

I want the new structure to be

B.x = [1 2 3;
       7 8 9];
B.y = [4 5 6;
       10 11 12];

These could also be a cell of structures if that makes things easier.

Answer 1

[Walter Roberson]

A(1).x = [1 2 3];
A(1).y = [4 5 6];
A(2).x = [7 8 9];
A(2).y = [10 11 12];

B.x = vertcat(A.x);
B.y = vertcat(A.y);

B

B = struct with fields:
    x: [2×3 double]
    y: [2×3 double]

Answer 2

[James Tursa]

F = fieldnames(A);
n = numel(F);
C = arrayfun(@(i)vertcat(A.(F{i})),1:n,'uni',false);
FC = [F';C];
B = struct(FC{:});
