first K eigenvalues?

Open Fil opened this issue 6 years ago • 3 comments

in EigenvalueDecomposition it would be nice to be able to retrieve only the first k eigenvalues & associated vectors, if it could save time and memory. I have no idea how to do it :)

Currently it's difficult to go beyond a 500x500 matrix.

I have no idea if the algorithm allows it :)

The nipals factorization allows you to retrieve one component at a time. It will be soon implemented in matrix.
