Follow-up Comment #18, bug #49523 (project octave): @Rik: I'm going to implement the NaN + i*0 version for both eigenvalues and eigenvectors. Now that eigs in octave is going to be in a good shape, I discovered that matlab switched to "A Krylov Schur algorithm for large eigenproblems". I found only a simple implementation around (https://github.com/dingxiong/KrylovSchur), so I think that matlab implemented it from scratch. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?49523> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
