POWER

 
Computes one or two eigenvalues of largest magnitude of a matrix, with
corresponding eigenvectors, using the power method. The user must provide a
starting guess for the eigenvector space, along with a subroutine to multiply the
matrix by a vector.
 
Classes  :  D4a2 . Real nonsymmetric matrix eigenvalue problems
            D4a7 . Sparse matrix eigenvalue problems
 
Type     : Fortran subroutine in NAPACK package.
Access   : Some uses prohibited. Portable.
Precision: Single.
 
Usage    : CALL POWER (EX, X, EY, Y, N, DIF, SIZE, NDIGIT, LIMIT, MULT)
 
Details  : Fullsource Source
Sites    : (1) NETLIB
