This iterative technique is described in great details in the book by Kenneth J. Beers, Numerical Methods for Chemical Engineering, Applications in Matlab, Cambridge University Press, 2007. It allows the determination of the largest and the smallest eigenvalues as well as any eigenvalue nearest to...
The function polyeig returns all the eigenvalues for the latter problem and thus this method is very slow to compute the largest eigenvalue. Is there a possibility to find only few largest eigenvalues? (In similar way like the function eigs for standard eigenvalue problem) thanks ...

I am trying to calculate the smallest real eigenvalues of a general problem A*V = B*V*D with sparse matrices using MKL and I have been having four problems when comparing to MATLAB: 1. I am always missing at least one of the smallest ei...
Eigenvalues of higher order have become an important topic of study in a new applied mathematics branch, numerical multilinear algebra, and they have a wide range of practical applications; for more references, see [7, 10, 11, 12]. In recent studies of numerical multilinear algebra [2, 3, ...
whereis a random vector from the uniform distribution on the unit sphere in. Assuming thatcan be diagonalized, we use its eigenvector matrixXto diagonalize. More precisely, we extract the joint eigenvaluesfrom the diagonal elements of.
A common way of finding the poles of a meromorphic function f in a domain, where an explicit expression of f is unknown but f can be evaluated at any given
in finding riccati solution of A*X+A'*X+X*W*X+Q that is I'm a little confused. What are the dimensions of these quantities? Are they matrices? Vectors? Scalars? EIGEN VALUE OF H ARE GIVEN BY= EIGENVALUES OF (A+W*x)& - (A+W*x); Is there some significance to ...
I've been using the powermethod (since it does not require matrix inversion) for computing the largest eigenvalue but in some cases it is extremely slow probably due the ratio of eigenvalues lamda2/lamda1 being close to 1. Can anyone suggest a better al...
As a first result, we obtained that the first five principal components were chosen among the others according to Kaiser's criterion, i.e., with corresponding eigenvalues greater than 1. Furthermore, we noticed that the percentage of the total variance explained by the first five principal ...
