I have to calculate the eigenvector and eigenvalues for many (more than 60.000) non-Hermitian 4x4 matrices. I know that this can be slightly speed up by means of using LinearAlgebra.LAPACK.geevx! instead of using the eigen() function itself. However, if I would do this in C++ and use the eigen libra…
