4 days ago · A special orthogonal matrix is an orthogonal matrix with determinant +1. As a linear transformation , every orthogonal matrix with determinant +1 is a pure rotation without reflection, i.e., the transformation preserves the orientation of the transformed structure, while every orthogonal matrix with determinant -1 reverses the orientation, i.e., is a composition of a pure reflection and a (possibly null) rotation.
5 days ago · All eigenvalues of an orthogonal projection are either 0 or 1, and the corresponding matrix is a singular one unless it either maps the whole vector space onto itself to be the identity matrix or maps the vector space into zero vector to be zero matrix; we do not consider these trivial cases.

3 days ago · Equivalently, this is the group of n x n orthogonal matrices, meaning that =, where denotes the transpose of a matrix. The orthogonal group has two connected components; the identity component is called the special orthogonal group S O ( n ) {\displaystyle \mathrm {SO} (n)} , consisting of the orthogonal matrices with determinant 1.
3 days ago · In the case of an orthogonal basis, the magnitude of the determinant is equal to the product of the lengths of the basis vectors. For instance, an orthogonal matrix with entries in R n represents an orthonormal basis in Euclidean space, and hence has determinant of ±1 (since all the vectors have length 1). The determinant is +1 if and only if ...
