Orthogonal matrix - Wikipedia
https://en.wikipedia.org/wiki/Orthogonal_matrixOverview. An orthogonal matrix is the real specialization of a unitary matrix, and thus always a normal matrix.Although we consider only real matrices here, the definition can be used for matrices with entries from any field.However, orthogonal matrices arise naturally from dot products, and for matrices of complex numbers that leads instead to the unitary requirement.
