Is there a way to use the trace of a matrix to find whether a set of matrices are orthogoal to one another?
The discussion focuses on using the trace of matrices to determine orthogonality among a set of matrices. It establishes that the trace function, defined as tr(AB) = tr(BA), plays a crucial role in this context. The conversation emphasizes the need to apply the definition of orthogonal matrices to fully understand the relationship between the trace and orthogonality. The participants clarify that while the trace is significant, it is not the sole criterion for determining orthogonality.
PREREQUISITESMathematicians, students of linear algebra, and anyone interested in advanced matrix theory and its applications in various fields.
