WebDescription. Given an n by n matrix A , function eigs () can calculate a specified number of eigenvalues and eigenvectors of A . Users can specify the selection criterion by argument which, e.g., choosing the k largest or smallest eigenvalues and the corresponding eigenvectors. Currently eigs () supports matrices of the following classes: matrix. http://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/ref/eigs.html
