WebWhere's the fallacy in my thinking: As I understand it, a square matrix whose determinant is not zero is invertible. Therefore, using row operations, it can be reduced to having all its column vectors as pivot vectors. That's equvialent to an upper triangular matrix, with the main diagonal elements equal to 1. WebRank of a Matrix. The above matrix has a zero determinant and is therefore singular. It has no inverse. It has two identical rows. In other words, the rows are not independent. If one row is a multiple of another, then they are not independent, and the determinant is zero. (Equivalently: If one column is a multiple of another, then they are not ...
