WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebImplementing the algorithm is then pretty straightforward: function fromVectors(u, v) { d = dot(u, v) w = cross(u, v) return Quaternion(d + sqrt(d * d + dot(w, w)), w).normalize() } The unit vector case For the case that \mathbf {u} u and \mathbf {v} v are already normalized unit vectors, the solution becomes much prettier:

Eigenvalues and eigenfunctions of an operator are defined as the solutions of the eigenvalue problem: A[un(→x)] = anun(→x) where n = 1, 2, . . . indexes the possible solutions. The an are the eigenvalues of A (they are scalars) and un(→x) are the eigenfunctions.
