A limit theorem for the eigenvalues of product of two random matrices - Yin, Krishnaiah - 1983 () Citation Context ...s, one has to find efficient bounds for the sums, S蟺(N), of products of entries of the deterministic matrices in order to determine their contribution to the limiting ...
To study the lower bound for the minimum eigenvalue and a upper bound for the spectral radius of Hadamard product of two irreducible M-matrices A and B , obtaining some new estimation of the bounds. These new bounds are only depend on the element of A and B, so they are easy to ...
Find the eigenvector of A corresponding to the other eigenvalue, λ=−1. In MATLAB, the command [V,D]=eig(A) will return two matrices: D and V. The elements of the diagonal matrix D are the eigenvalues of the square matrix A. The columns of the matrix V are the corresponding eig...

The characteristic polynomial (of degree 8) factors nicely into the product of two linear terms and three quadratic terms. You can see immediately that four of the eigenvalues are 0, 1020, and a double root at 1000. The other four roots are obtained from the remaining quadratics. Use ...
This paper first introduces the background, then discusses the lower bounds for the minimum eigenvalue of the Hadamard product * of two nonsingular M-matrices *B by using Cauchy-Schwitz inequality*, Jacobi iterative matrix and the relationship between matrix eigenvalue and eigenvector and obtains ...
Relating the problem of the probability that the product of two real 2 dimensional random matrices has real eigenvalues to an issue of optimal quantum entanglement, this is fully analytically solved. It is shown that in $\\pi/4$ fraction of such products the eigenvalues are real. Being ...
For matrices of size 2×2, the characteristic polynomial is of degree 2 and there are therefore 2 roots (if you count complex roots and take multiplicity of roots into account). In Example 10.5, the two roots (2 and 3) are different and there is a basis of eigenvectors. The same holds...
Since it is the sum of the eigenvalues, it is the same for similar matrices, and hence it can be considered a property of a linear transformation. The characteristic polynomial of a direct sum of matrices is the product of their characteristic polynomials: ...
A particularly important property of matrices is the multiplication process, which is different than the multiplication operation ofarithmetics. Two matrices can only be multiplied if their dimensions are compatible, which means the number of columns in the first matrix is the same as the number of...
