GAMS Module CPBEQU in LAPACK


CPBEQU

 
Computes row and column scalings to equilibrate a complex Hermitian positive
definite band matrix and reduce its condition number. (Computational routine.).
 
Classes  :  D2d2 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (complex
                 Hermitian positive definite banded matrices)
 
Type     : Fortran subroutine in LAPACK package.
