Estimates the 1-norm condition number of a tridiagonal matrix. The matrix must first be factored using NAPACK subroutine TFACT. Classes : D2a2a . Solution of systems of linear equations, including matrix inverses, and LU and related factorizations (real nonsymmetric tridiagonal matrices) Type : Fortran subroutine in NAPACK package. Access : Some uses prohibited. Portable. Precision: Single. Usage : S = TCON (L, D, U, B) See also : TFACT Details : Fullsource Source Sites : (1) NETLIB
