WebJan 19, 2024 · A rotation matrix is always a square matrix with real entries. This implies that the rotation matrix will always have an equal number of rows and columns. Moreover, rotation matrices are orthogonal matrices with a determinant equal to \(1\). Consider a square matrix \(R\). Then \(R\) is said to be rotation matrix if and only if: \(R^{T} = R^{-1 ... WebThe set of all rotation matrices is called the special orthogonal group SO(3): the set of all 3x3 real matrices R such that R transpose R is equal to the identity matrix and the determinant of R is equal to 1. Rotation matrices satisfy the following properties: The inverse of R is equal to its transpose, which is also a rotation matrix.
