Elements of anti diagonal
WebAn anti diagonal matrix is just the mirror image of a diagonal matrix with respect to the placement of the elements. i.e., in an anti-diagonal matrix, all the elements above and below the diagonal (which is NOT the principal diagonal) are zeros. WebMay 10, 2024 · $\begingroup$ The determinant of this one and the one in which the zeros are in the main diagonal differ by a power of $(-1)$ factor, specifically $(-1)^{\frac{n(n-1)}{2}}$, one $-1$ for each column transposition necessary to turn one into the other. The determinant of that one is easier to compute, since $-1$ is an eigenvalue with …

The question is the next: Show that the elements of the diagonal of an antisymmetric matrix are 0 and … WebDec 23, 2024 · My task is to check if the elements of main and anti diagonal of quadratic matrix are same. If this condition is satisfied 'Yes' should be printed; 'No' in the opposite case. For example, the condition is satisfied for matrix 3x3 with all rows equal to: 1 2 3. My code worked for all the matrices except the one with negative numbers and the one ...
WebDec 21, 2024 · The trace of an anti diagonal matrix is still the sum of the [main] diagonal elements. If n is even, then the trace is zero since all diagonal elements are zero. If n is odd, then the n + 1 2, n + 1 2 element at the very center of the matrix is the only element on both the main diagonal and anti diagonal, so the trace is equal to this element. WebApr 4, 2024 · , the ISM summation can be interpreted as a sum over the anti-diagonal elements of the reflection matrix . Such a line summation [ Fig. 1(a) , left inset] is analogous to a line projection performed in many tomographic imaging techniques, such as x …
