WebSep 24, 2010 · That is, if O is an orthogonal matrix, and v is a vector, then ‖ O v ‖ = ‖ v ‖. In fact, they also preserve inner products: for any two vectors u and v you have. O v O u = v O † O u = v u . Actually, it is more true to say that the eigenvalues of orthogonal matrices have complex modulus 1. They lie on the unit circle in the ... WebA rotation matrix is always a square matrix with real entities. This implies that it will always have an equal number of rows and columns. Moreover, rotation matrices are orthogonal matrices with a determinant equal to 1. Suppose we have a square matrix P. Then P will be a rotation matrix if and only if P T = P-1 and P = 1.
