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?(adsbygoogle = window.adsbygoogle || []).push({});

If it helps to know, it's a Hamiltonian and I want to find energies and wavenfunctions.

Thanks.
