WebActually, if the row-reduced matrix is the identity matrix, then you have v1 = 0, v2 = 0, and v3 = 0. You get the zero vector. But eigenvectors can't be the zero vector, so this tells you that this matrix doesn't have any eigenvectors. To get an eigenvector you have to have (at least) one row of zeroes, giving (at least) one parameter.
