Classical Hamiltonian Quaternions - Other Operators in Detail - Axis and Angle
... quaternion is viewed as the quotient of two vectors, then the axis of the quaternion is a unit vector perpendicular to the plane of the two vectors in this original ... The angle is the angle between the two vectors ...
SIC-POVM - Relation To Spherical T-designs
... A spherical t-design is a set of vectors on the d-dimensional generalized hypersphere, such that the average value of any -order polynomial over is ... and as the t-fold tensor product frame operator, it can be shown that a set of normalized vectors with forms a spherical t-design if and only if It then immediately follows ...
Self-similarity Matrix - Definition
... first transforms a data series into a an ordered sequences of feature vectors, where each vector describes the relevant features of a data series in a given local interval ... by computing the similarity of pairs of feature vectors where is a function measuring the similarity of the two vectors, for instance, the inner product ... Then similar segments of feature vectors will show up as path of high similarity along diagonals of the matrix ...
