How to Use a For Loop to Dynamically Assign the Values of Struct Fields to a Matrix?

How to use a for loop to dynamically assign the values of fields C, D, and G to a matrix?

if for loop is not possible, what else can do it? Imagine I have many fields and want it to be done programmatically

A.B.C = [1 2 3];
A.B.D = [4 5 6];
A.B.E = [7 8 9];

so the final matrix looks like:

1 2 3
4 5 6 
7 8 9

cell2mat(structfun(@(f) {f}, A.B))

would work
