Create matrix with two matrices

Hello, I have two matrices that I want to combine to form another one as in the example below:

A = [1 2 3; 4 5 6;7 8 9]

B = [ 11 12 13;14 15 16;17 18 19]

Matrix = [1 2 3 ; 11 12 13 ; 4 5 6 ; 14 15 16 ; 7 8 9 ; 17 18 19]

Can anyone help me to solve it?

Many thanks,

Eva

A = [1 2 3; 4 5 6;7 8 9]
B = [ 11 12 13;14 15 16;17 18 19]

m = size(A,1)+size(B,2) ;
C = zeros(m,3) ; 
C(1:2:end,:) = A ; 
C(2:2:end,:) = B ;

You can do something like this

A = [1 2 3; 4 5 6;7 8 9];
B = [ 11 12 13;14 15 16;17 18 19];
Matrix = zeros(size(A,1)+size(B,1), size(A,2));
Matrix(1:2:end, :) = A;
Matrix(2:2:end, :) = B;
