How can I add elements of an array to another array?

A = [1 2; 3 4];

B = [1 , 1];

How can I add the elements of B to A randomly? For example A becomes: A =[2 2 ; 4 4]; OR A = [1 3; 5 4];

Not really clear on why you'd want to do this, but this would work:

randindices = randperm(numel(A), numel(B));
A(randindices) = A(randindices) + B
