How to maintain the positive semidefinite of the matrix when multiplying another matrix? For a given matrix A , does x^T A x 0, \text{ for any } x imply that A is positive definite? How to check if a symmetric matrix is negative definite?
my wish to get the specific matrix: B = [1 2 3 8 1 6 ; 2 1 0 3 5 7; 3 0 1 4 9 2; 8 3 4 1 0 3 ; 1 5 9 0 1 2; 6 7 2 3 2 1] my intuition is to found some legality or somthing like that, and to use it to get a simple solution(1 row with the shortest...
A matrix that has the same number of rows and columns is known as a Square matrix. A matrix, when multiplied by its inverse, gives an Identity matrix.Answer and Explanation: Consider a complex square matrix {eq}H {/eq}. Now, this matrix is said to be unitary only if the conjugate tr...
I am wondering how to get binary variable matrix that is symmetric to the diagonal. The matrix looks like this: [y1 y2 y3 y4 y2 y3 y3 y4 y3 y3 y3 y4 y4 y4 y4 y4] The upper and lower triangle of the matrix is the same, meaning that the corresponding element of the upper ...

An undirected network only needs half of the matrix. If the network is weighted, every edge in the list needs an additional weight value to be stored. In the matrix, elements just become weight values, whereby a weight of 0 symbolizes no edge. Most graph algorithms can be applied on both...
