First step is to compute y=(L+D)*x and second step is to compute y=L^T*x + y. Given the fact that the transpose operation y=L^T*x is 10x slower than non-transpose version y=L*x, the symmetric property does not show up any performance gain. brownies with chocolate chips on topWebEigenvalues and Eigenvectors Definition 1: Let A∈ℜn×nbe a square matrix.
