ECON

 
Estimates the 1-norm condition number of an upper Hessenberg matrix. The matrix
must first be factored using NAPACK subroutine EFACT.
 
Classes  :  D2a3 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (real
                 nonsymmetric triangular matrices)
 
Type     : Fortran subroutine in NAPACK package.
Access   : Some uses prohibited. Portable.
Precision: Single.
