Suppose I have a matrix a:
a = [2,3;1,2;1,2;0,1;1,2;3,1;1,3;2,1;2,3;3,1];
I want to build matrix b with dimension 2*2 that first row is sum up of all odd rows of matrix a and second rwo is sum up of all even rows of matrix a
b = [16;19]

OK, suppose you do. Is this homework? This is very very simple. What have you tried?

Here is a hint. Do you know how to make a vector of odd numbers? Even numbers?
