Function/Subroutine Documentation
   subroutine sget03 (integer n, real, dimension( lda, * ) a, integer lda,
       real, dimension( ldainv, * ) ainv, integer ldainv, real, dimension(

       SGET03

       Purpose:


           !>
           !> SGET03 computes the residual for a general matrix times its inverse:
           !>    norm( I - AINV*A ) / ( N * norm(A) * norm(AINV) * EPS ),
           !> where EPS is the machine epsilon.
           !>
