Orthogonal matrix is a real square matrix whose product, with its transpose, gives an identity matrix. When 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. solingen hasencleverstraße
