ICON

 
Estimates the 1-norm condition number of a symmetric matrix. The matrix must
first be factored using NAPACK subroutine IFACT.
 
Classes  :  D2b1a . Solution of systems of linear equations, including matrix
                  inverses, and LU and related factorizations (real
                  symmetric indefinite matrices)
 
Type     : Fortran subroutine in NAPACK package.
Access   : Some uses prohibited. Portable.
Precision: Single.
 
Usage    : S = ICON (A, B)
