It has the important property that when the cross product For the crossed product in algebra and functional analysis, see crossed product. ...
is written with the matrix multiplication (A is a orientation matrix), this matrix is a skew-symmetric matrix with zeros on the main diagonal and plus and minus the components of the angular velocity as the other elements, In linear algebra, a skew-symmetric (or antisymmetric) matrix is a square matrix A whose transpose is also its negative; that is, it satisfies the equation: AT = −A or in component form, if A = (aij): aij = − aji for all i and j. ...
