CHBGST.C

 
Reduces a complex Hermitian definite banded generalized eigenproblem A * x =
lambda * B * x to standard form C * y = lambda * y, such that C has the same bandwidth as A.
B must have been previously factorized by CPBSTF. [C version of LAPACK routine,
converted from Fortran by f2c.].
 
Classes  :  D4b3 .  Complex Hermitian generalized matrix eigenvalue problems
            D4b5 .  Banded generalized matrix eigenvalue problems
            D4c1c . Standardize matrix eigenvalue problem
 
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.
 
Usage    : int chbgst_(char *vect, char *uplo, integer *n, integer *ka,
