Function/Subroutine Documentation

  subroutine alaerh (character*3 path, character*( * ) subnam, integer info, integer infoe, character*( * ) opts, integer m, integer n, integer kl, integer ku, integer n5, integer imat, integer nfail, integer nerrs, integer nout)

ALAERH

Purpose:

     ALAERH is an error handler for the LAPACK routines.  It prints the
     header if this is the first error message and prints the error code
     and form of recovery, if any.  The character evaluations in this
     routine may make it slow, but it should not be called once the LAPACK
     routines are fully debugged.

Parameters
    PATH

              PATH is CHARACTER*3
              The LAPACK path name of subroutine SUBNAM.

    SUBNAM

              SUBNAM is CHARACTER*(*)
              The name of the subroutine that returned an error code.

    INFO

              INFO is INTEGER
              The error code returned from routine SUBNAM.

    INFOE

              INFOE is INTEGER
              The expected error code from routine SUBNAM, if SUBNAM were
              error-free.  If INFOE = 0, an error message is printed, but
              if INFOE.NE.0, we assume only the return code INFO is wrong.

    OPTS

              OPTS is CHARACTER*(*)
              The character options to the subroutine SUBNAM, concatenated
              into a single character string.  For example, UPLO = 'U',
              TRANS = 'T', and DIAG = 'N' for a triangular routine would
              be specified as OPTS = 'UTN'.

    M

              M is INTEGER
              The matrix row dimension.

    N

              N is INTEGER
              The matrix column dimension.  Accessed only if PATH = xGE or
              xGB.

    KL

              KL is INTEGER
              The number of sub-diagonals of the matrix.  Accessed only if
              PATH = xGB, xPB, or xTB.  Also used for NRHS for PATH = xLS.

    KU

              KU is INTEGER
              The number of super-diagonals of the matrix.  Accessed only
              if PATH = xGB.

    N5

              N5 is INTEGER
              A fifth integer parameter, may be the blocksize NB or the
              number of right hand sides NRHS.

    IMAT

              IMAT is INTEGER
              The matrix type.

    NFAIL

              NFAIL is INTEGER
              The number of prior tests that did not pass the threshold;
              used to determine if the header should be printed.

    NERRS

              NERRS is INTEGER
              On entry, the number of errors already detected; used to
              determine if the header should be printed.
              On exit, NERRS is increased by 1.

    NOUT

              NOUT is INTEGER
              The unit number on which results are to be printed.
