Web25 mar 2024 · As expected, when carefully implemented, the rank-one update method is lightning fast. I suspect that this mistake is quite common. By default, multiplication is a left-associative operation. This case results in an unnecessary matrix-matrix product instead of an outer-product of two matrix-vector products. WebDescription.
