Hi guys I am in a situation, where I have to diagonalize very large matrices. My experience with Mathematica is limited, but what I need is the entire set of eigenvalues. From what I have read, this excludes the use of ARPACK, since this is used to find certain eigenvalues (i.e. largest, smallest etc.). I read that LAPACK is used to find entire sets of eigenvalues, but the Mathematica-help does not say much on this subject. So to make a long story short: What is the most effective way of finding the entire set of eigenvalues (and corresponding eigenvectors) of a very large matrix? Best regards, Jim L
