Webb1 sep. 2024 · To demonstrate the unique properties of our new method, we investigate TC assimilation with a long covariance length scale that would be impractical for local analysis methods. As we show, the matrix function method is roughly comparable in terms of wall-time performance to AC07 and far superior to S17. Webb13 okt. 2024 · In general a symmetric 3 × 3 matrix will have the form: A = ( a b c b d e c e f) which has a determinant of a ( d f − e 2) + b ( c e − b f) + c ( b e − d c). Even worse-looking. The only time it really gets a lot simpler is if you have zeroes in there. The simplest way to calculate is not to calculate. Share Cite Follow edited Jul 14, 2024 at 6:30
