Definition:Pairwise Orthogonal/Rows

Definition
Let $\sqbrk a_{m n}$ be a matrix of order $m \times n$.

The rows of $\sqbrk a_{m n}$ are described as pairwise orthogonal :


 * $\forall i, j \in \set {1, 2, \ldots, m}, i \ne j: {r_i}^\intercal \cdot {r_j}^\intercal = 0$

That is, the dot product of each pair of distinct rows of $\sqbrk a_{m n}$, when transposed and considered as vectors, is zero.
