DGEDI

 
Uses LU factorization of general double precision matrix to compute its
determinant and/or inverse.
 
Classes  :  D3a1 . Determinants of general real nonsymmetric matrices
            D2a1 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (general real
                 nonsymmetric matrices)
 
Type     : Fortran subroutine in CMLIB library (LINPAKD sublibrary).
Access   : Public domain. Portable.
Precision: Double.
 
Usage    : CALL DGEDI(A,LDA,N,IPVT,DET,WORK,JOB)
