First let me say thank so much for this discussion. I read the whole thread and most of my questions were answered. I have some new ones though: 1. I will graduate next year with a PhD in Quantum Chemistry and MS in ECE. I know my way around numerical methods, simulations, etc. My C++ is...

I misspoke, it's not a 4D matrix, it's an N by N by N by N matrix. So there are ijkl indices.

I have a symmetric NxNxNxN matrix that I need to find eigenvalues a eigenvectors for. All the BLAS routines are for NxN matrices and I can't find anything that would work on a 4D matrix. Any tricks you guys know of? If it helps to know, it's a Hamiltonian and I want to find energies and...
