I have a variance-covariance matrix W with diagonal elements diag(W). I have a vector of weights v. I want to scale W with these weights but only to change...
I have an exapmle below which gets the product of the fisrt row an N columns. I am new to mathlab. Using a for loop like below, how can I multiply diagonal elements of a matrix NxN? thank you NxN rowelements= 1 ; product = 1.0 ; ...
I have a square matrix and would like to make the diagonal elements zero, as well as select elements that are off-diagonal. For the latter, I only want the elements next to (one removed from) the diagonal to be zero, e.g., I would want A(5,6) and A(6,...
Here, we are going to learn how to find the sum of main and opposite diagonal elements of a matrix in C programming language? Submitted byNidhi, on July 14, 2021 Problem statement Given a matrix, we have to find the sum of main and opposite diagonal elements of a matrix using C...
Let A be a skew-symmetric matrix. Then by definition A'=-Athe (i, j)th element of A' = the (i, j)th element of(- A)→the (j,i)th element of A= -the (i, j)th element of AFor the diagonal elements i= j二the (i,i)th element of A=- -the (i,i)th elementthe (i...
