LAPACK Linear Equation Computational Routines

Table
"Computational Routines for Systems of Equations with Real Matrices"
lists the LAPACK computational routines
(FORTRAN 77 and Fortran 95 interfaces)
for factorizing, equilibrating, and inverting real matrices, estimating their condition numbers, solving systems of equations with real matrices, refining the solution, and estimating its error. Table "Computational Routines for Systems of Equations with Complex Matrices" lists similar routines for complex matrices.
Respective routine names in the Fortran 95 interface are without the first symbol (see Routine Naming Conventions ).
