WebApr 20, 2024 · The issue is not with creating the A matrix actually. The issue is with creating the upper diagonal. I can create the A. For example let's consider A is a matrix of one's. For c=3,g=1, the first block of upper diagonal block will be zero matrix of order 4*3, and A matrix of one's order 4*3. Then in the second block the size will reduced now by one. WebMar 23, 2024 · I was hoping to have a tensor_diag function that takes a tensor A as an input parameter and returns a vector consisting of its diagonal elements. 3 Comments Show Hide 2 older comments

WebQuestion: Given A is a square matrix, find the sum of the anti-diagonal of A. The anti-diagonal of a matrix is the one that leads from the top-right to the bottom-left. For example, if the given matrix is A = [13 23 0 3 17 13 7 0 0 -11 19 23 5 0 17 19] then the sum of the anti-diagonal elements is = A (1, 4) +A (2, 3) +A (3, 2) +A (4, 1) = 3 + 7 + (-11) +5 = 4 WebMar 26, 2015 · Mar 27, 2015 at 17:37 possible duplicate of Vectorizing sums of different diagonals in a matrix – Robert Seifert Mar 27, 2015 at 17:46 Add a comment 2 Answers … flipcase für iphone 8plus
