I have two large matrices having different rows. for instanc, consider:
A=[1 2; 3 4; 5 6; 7 8; 9 0];
B=[7 5; 2 3];
Result=[8 7; 5 7; 12 11; 9 11; 16 5]
Now i want to add A and B such that: 1st row add with 1st, 2nd row with 2nd, 3rd row with 1st again, 4th row with 2nd again and so on. the process repeat till end.
Thanks in advance.
