WebAug 28, 2012 · With several examples I've tried of "small" k, I get 44seconds vs 18seconds (eigsh being the faster), when k=2 they are approximately the same, when k=1 (strangely) or k is "large" eigsh is considerably slower, in all cases eigh takes around 44seconds. There must be more efficient algorithm to do this, which you would expect could find the largest …
