CGBCON.C

 
Estimates the reciprocal of the condition number of a general band matrix, in
either the 1-norm or the infinity-norm, using the LU factorization computed by
CGBTRF. (Computational routine.). [C version of LAPACK routine, converted from
Fortran by f2c.].
 
Classes  :  D2c2 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (complex
                 non-Hermitian 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 cgbcon_(char *norm, integer *n, integer *kl, integer *ku,
           complex *ab, inte ger *ldab, integer *ipiv, real *anorm, real
           *rcond, complex *work, real *rwork , integer *info)
