Rank-one update

Tīmeklis2024. gada 25. maijs · For a rank-one update of a dense matrix in Matlab, I would write A=A+u*v'. If I just use the same Matlab statement in Julia, I’ll get poor performance because of needless memory allocation and copying. I know how to write this with loops to get performance, and I also know how to write it without explicit loops using the … TīmeklisThis inverse problem is basically a least square problem with a rank-1 update. x = [ u v T + H H H] − 1 H H b. There are two objectives, one can be achieved with the least square problem and the other with the rank-1 update. I need to find the best tradeoff between the two. The least square solution (without the rank-1 update) needs to be ...

These multiplications can be done cheaply without forming $\frac{1}{n-1}(M^TM-n\mu\mu^T)$ explicitly. Where to find a software package that does this, though, I'm not sure. $\endgroup$ –
