776

 
SRRIT: Calculates the dominant invariant subspace of a nonsymmetric matrix.
Designed to solve eigenvalue problems involving large, sparse nonsymmetric
matrices. (See Z. Bai and G.W. Stewart, ACM TOMS 23 (1997) pp. 494-513.).
 
Classes  :  D4a2 . Real nonsymmetric matrix eigenvalue problems
            D4a7 . Sparse matrix eigenvalue problems
 
Type     : Fortran software in TOMS collection.
Access   : Some uses prohibited. Portable.
Precision: Single or double.
 
Usage    : CALL SRRIT (N, NV, M, MAXIT, ISTART, Q, LDQ, AQ, LDA, T, LDT, WR, WI,
           RSD, ITRSD, IWORK, WORK, LWORK, INFO, EPS, ATQ)
