It would be a great addition to this series to show us how to compute those Jacobi rotation matrices from the three elements of A^TA. I tried to find such video in these lectures, and perhaps I missed it but I couldn't find it. And exactly what are the next three elements in the sweep? And how come that now it is not numerically unstable to compute ai^Taj, as these are the all elements of A^TA, or are they? It seems to me that they should be, but you told us that these can be unstable computations... what am I not getting right?. Thanks for the answers.
perfect explanation, thank you very much!
