Now I'm testing it on a few millions of random Gaussian matrices plus on some degenerate cases. If it works out to my satisfaction, I'll post the code with which (I hope) you will be happy :) | |
| Nov 22, 2022 at 3:41 | comment | added | fedja | I'll try both methods when I have time and see if I agree with you on the speeds (I'm especially concerned about the scenario when $L$ is nearly singular). Unfortunately, it seems like it'll have to wait until the Thanksgiving is over :-) | |
