CGEESX.C

 
Computes the eigenvalues and Schur factorization of a general matrix, orders the
factorization so that selected eigenvalues are at the top left of the Schur form,
and computes reciprocal condition numbers for the average of the selected
eigenvalues, and for the associated right invariant subspace. (Expert
driver.). [C version of LAPACK routine, converted from Fortran by f2c.].
 
Classes  :  D4a4 . Complex non-Hermitian matrix eigenvalue problems
 
Type     : C subroutine in CLAPACK package.
Access   : Public domain. Portable.
Precision: Single.
Note     : For best results, CLAPACK developers prefer that you download and
           install the entire CLAPACK library on your system. To do this, see the 
           netlib CLAPACK distribution for details.
