You are given a N X N integer matrix. You have to find the sum of all the main diagonal elements of A. Main diagonal of a matrix A is a collection of elements A[i, j] such that i = j. Input Format ...

Diagonalisation of a matrix is the process of reduction of a matrix to diagonal form. The process of reduction of a matrix to diagonal form is as follows: A square matrix of order n with n linearly ...

In this paper it is shown that, given a complex square matrix A all of whose leading principal minors are nonzero, there is a diagonal matrix D such that the product DA of the two matrices has all its ...
