Diagonalize a symmetric matrix from matlab
WebSep 7, 2024 · The small norm of the input matrix does not matter, as scaling is likely applied in such a case. Since the real symmetric matrix features eigenvalues of very different magnitude (from 3.16224604e-63 to 3.16230928e-03), it is ill-conditionned. The accuracy of most linear algebra procedures, including eigenvalue computation, is significantly ...
