  1. Apr 29, 2009 #1
    Is there a way to use the trace of a matrix to find whether a set of matrices are orthogoal to one another?

    Is the trace the only thing known ?
    You just have trace = x ?

    Since tr(AB) = tr(BA) (sorry wrong terminology), so just apply the definition of an orthogonal matrix.
