merge two arrays with different size

hi, if I have two arrays, each one has different size ex a(1:1000,1:20) b(1:1000,1:30)

I want to merge them to one array as follow c=[a;b]; how I can make them with the same size , merge them thanks

A = rand(10, 20);
B = rand(10, 30);
[sA1, sA2] = size(A);
[sB1, sB2] = size(B);

C(sA1+1:sA1+sB1, 1:sB2) = B;
C(1:sA1, 1:sA2)         = A;

This works if B has more or less columns than A.
