ZGET03

Function/Subroutine Documentation

  subroutine zget03 (integer n, complex*16, dimension( lda, * ) a, integer lda, complex*16, dimension( ldainv, * ) ainv, integer ldainv, complex*16, dimension( ldwork, * ) work, integer ldwork, double precision, dimension( * ) rwork, double precision rcond, double precision resid)

ZGET03

Purpose:

     ZGET03 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.

Parameters
    N

              N is INTEGER
              The number of rows and columns of the matrix A.  N >= 0.

    A

              A is COMPLEX*16 array, dimension (LDA,N)
              The original N x N matrix A.

    LDA

              LDA is INTEGER
              The leading dimension of the array A.  LDA >= max(1,N).

    AINV

              AINV is COMPLEX*16 array, dimension (LDAINV,N)
              The inverse of the matrix A.

    LDAINV

              LDAINV is INTEGER
              The leading dimension of the array AINV.  LDAINV >= max(1,N).

    WORK

              WORK is COMPLEX*16 array, dimension (LDWORK,N)

    LDWORK

              LDWORK is INTEGER
              The leading dimension of the array WORK.  LDWORK >= max(1,N).

    RWORK

              RWORK is DOUBLE PRECISION array, dimension (N)

    RCOND

              RCOND is DOUBLE PRECISION
              The reciprocal of the condition number of A, computed as
              ( 1/norm(A) ) / norm(AINV).

    RESID

              RESID is DOUBLE PRECISION
              norm(I - AINV*A) / ( N * norm(A) * norm(AINV) * EPS )
