(SGECON/DGECON) estimates the condition number of a real matrix A, where A has been factorized by F07ADF (SGETRF/DGETRF). Classes : D2a1 . Solution of systems of linear equations, including matrix inverses, and LU and related factorizations (general real nonsymmetric matrices) Type : Fortran subroutine in NAG library (F07 sublibrary). Access : Proprietary. Many implementations available. Precision: Double. Usage : CALL F07AGF(NORM, N, A, LDA, ANORM, RCOND, WORK, IWORK, INFO) See also : F07ADF Details : Documentation Example Example-input Example-output Sites : (1) AIX (2) ITL
