CPBEQU.C

 
Computes row and column scalings to equilibrate a complex Hermitian positive
definite band matrix and reduce its condition number. (Computational
routine.). [C version of LAPACK routine, converted from Fortran by f2c.].
 
Classes  :  D2d2 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (complex
                 Hermitian positive definite banded matrices)
 
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 cpbequ_(char *uplo, integer *n, integer *kd, complex *ab,
           integer *ldab, re al *s, real *scond, real *amax, integer *info)
