Dot product of equal vectors

WebWhen two vectors are said to be orthogonal, it means that they are perpendicular to each other. When these vectors are represented in matrix form, their product gives a square matrix. A square matrix is said to be orthogonal when it comprises real elements and its transpose is equal to its inverse. In other words, when the product of the real ...
