Size and Rank of Matrix A is given as 10 * 3 and 3 respectively. Actual/Full Matrix B is given which is of size 3 * 3 and I am able to find that the rank of B is also 3.
I have to find the actual rank of the product matrix AB.
I understand that rank(AB)≤min(rank A,rank B) as per theorem. But need help to find the exact rank.
