517

 
CONDIT and QR2NOZ: a Fortran subroutines for computing the condition numbers of
matrix eigenvalues without computing eigenvectors. (See S.P. Chan, R. Feldman,
and B.N. Parlett, ACM TOMS 3 (1977) pp. 186-203.).
 
Classes  :  D4c2b . Compute eigenvalues of Hessenberg matrix
 
Type     : Fortran software in TOMS collection.
Access   : Some uses prohibited. Portable.
Precision: Single.
 
Usage    : CALL CONDIT (NM, N, A, V1, V2, WI, COND) AND CALL QR2NOZ (NM, N, LOW,
           IGH, H, WR, WI, IERR)
 
Details  : Fullsource
