当一个矩阵的行数 与列数 相等时,该矩阵称为一个n阶方阵square matrix。对于方阵,从左上角到右下角的连线,称为主对角线main diagonal。若一个阶方阵的主对角线上的元素都是,而其余元素都是零,则称为单位矩阵identity matrix,记为En或In,即: 。如一个阶方阵的主对角线上(下)方的元素都是零,则称为下(...

Main Diagonal In subject area: Engineering A magic square is an arrangement of the numbers from 1 to n2 in an “n × n” matrix, with each number occurring exactly once, such that the sum of the entries of any row, any column, or any main diagonal is the same. From: Solar Energy,...

For a Toeplitz matrix (a polynomial in the shift S), a zero winding number is the key. A wider class of structured matrices was analyzed by de Boor [7]. For Fredholm operators in general, Israel Gohberg's diplomatic answer to this question was that every diagonal has the right to be ...
摘要: Recently some generalizations of Sylvester type tridiagonal matrices have been considered with their spectra. We introduce a new kind generalization of Sylvester type tridiagonal matrix by considering its main diagonal entries. Then we compute its spectra and determinant....

This chapter focuses on the main diagonal of a bi-infinite band matrix. It is shown how to single out a particular diagonal of a bi-infinite band matrix A as its main diagonal, using the de-composition of the solution set of Ax = 0 into those that are bounded at ∞ and ∞. As an...
