WebRank of a matrix: Gaussian method. The rank of a matrix is the number of linearly independent rows of that matrix. A row is linearly independent from the other rows when it is not the result of a linear combination of them. So, if we can find a row that is a linear combination of other rows, we will say that this row is linearly dependent.
