8.In this paper, a kind of inverse eigenvalue problem which is the reconstruction of real symmetric five-diagonal matrix by five eigenvalues and corresponding eigenvectors is proposed. 本文讨论了一类由五个特征值和相应特征向量构造实对称五对角矩阵的特征值反问题。
copies of ξ. (diagonal entries) {wii:1≤i≤n} is a collection of i.i.d. copies of ζ. If ξ and ζ have the same distribution, we say W is a Wigner matrix with atom variable ξ. We will always assume that ξ is non-degenerate, namely that there is no value c such that P...
{/eq} In order to compute {eq}\lambda_{i}, 1\leq{i}\leq{n}, {/eq} one solves the characteristic equation {eq}|A-\lambda{I}|=0, {/eq} where {eq}I {/eq} denotes the identity matrix—the square matrix with ones along the primary diagonal and zeroes elsewhere—and the vertical...

main diagonal when A is triangular; so we need to transform A into a diagonal or triangular matrixwithout changing its eigenvalues.However, Gaussian factorizstion A=LU is not suited to this purpose. The eigenvalue of U may be visible on the diagonal, but they are not the eigenvalues of A...
We establish a general relation between the diagonal correlator of eigenvectors and the spectral Green's function for non-hermitian random-matrix models in the large-N limit. We apply this result to a number of non-hermitian random-matrix models and show that the outcome is in good agreement ...
