WebOct 11, 2024 · In your picture, you use 3 row operations to get to A ′, so E = E 1 E 2 E 3 and we have. E A = A ′. Now we can solve for A and see. A = E − 1 A ′. Note that A ′ can be written as the product of a diagonal matrix and an upper triangular matrix with 1 on the diagonals, A ′ = D U = [ 1 0 0 0 2 0 0 0 2] [ 1 0 1 0 1 0 0 0 1]. WebTo multiply two matrices together the inner dimensions of the matrices shoud match. For example, given two matrices A and B, where A is a m x p matrix and B is a p x n matrix, you can multiply them together to get a new m x n matrix C, where each element of C is the dot product of a row in A and a column in B.

WebOct 15, 2016 · This one line version takes roughly half the time when I use 2048 coordinates (4 s instead of 10 s) but this is doing twice as many calculations as it needs in order to get the symmetric matrix. Is there a way to adjust the one line command to only get the triangular matrix (and the additional 2x speedup, i.e. 2 s)?
