The rank of a Matrix , is determined by the number of independent rows or columns ..Fine .. here's a matrix ..

A = 2 4 1 3

-1 -2 1 0

0 0 2 2

3 6 2 5

Apparently " the second column is twice the first column, and that the fourth column equals the sum of the first and the third. The first and the third columns are linearly independent, so the rank of A is two "

here is the part where I am getting confused .. what if I consider the rows ..I see that all rows are linearly independent ... If somebody coudl explain this to me please ...

Thanks a lot
