WebEigenvalues and Eigenvectors. For a matrix transformation T T, a non-zero vector v\, (\neq 0) v( = 0) is called its eigenvector if T v = \lambda v T v = λv for some scalar \lambda λ. This means that applying the matrix transformation to the vector only scales the vector. WebIn mechanics and geometry, the 3D rotation group, often denoted SO(3), is the group of all rotations about the origin of three-dimensional Euclidean space under the operation of composition.. By definition, a rotation about the origin is a transformation that preserves the origin, Euclidean distance (so it is an isometry), and orientation (i.e., handedness of space).
