low RAM consuming c++ eigen solver
问题 I'm newbie in C++ programming , but I have a task to compute eigenvalues and eigenvectors (standard eigenproblem Ax=lx ) for symmetric matrices (and hermitian)) for very large matrix of size: binomial(L,L/2) where L is about 18-22. Now I'm testing it on machine which has about 7.7 GB ram available, but at final I'll have access to PC with 64GB RAM. I've started with Lapack++ . At the beginning my project assume to solve this problem only for symmetrical real matrices. This library was great.
