SDRVGT

SDRVGT

Purpose:

 SDRVGT tests SGTSV and -SVX.

Parameters

DOTYPE

          DOTYPE is LOGICAL array, dimension (NTYPES)
          The matrix types to be used for testing.  Matrices of type j
          (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
          .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.

NN

          NN is INTEGER
          The number of values of N contained in the vector NVAL.

NVAL

          NVAL is INTEGER array, dimension (NN)
          The values of the matrix dimension N.

NRHS

          NRHS is INTEGER
          The number of right hand sides, NRHS >= 0.

THRESH

          THRESH is REAL
          The threshold value for the test ratios.  A result is
          included in the output file if RESULT >= THRESH.  To have
          every test ratio printed, use THRESH = 0.

TSTERR

          TSTERR is LOGICAL
          Flag that indicates whether error exits are to be tested.

A

          A is REAL array, dimension (NMAX*4)

AF

          AF is REAL array, dimension (NMAX*4)

B

          B is REAL array, dimension (NMAX*NRHS)

X

          X is REAL array, dimension (NMAX*NRHS)

XACT

          XACT is REAL array, dimension (NMAX*NRHS)

WORK

          WORK is REAL array, dimension
                      (NMAX*max(3,NRHS))

RWORK

          RWORK is REAL array, dimension
                      (max(NMAX,2*NRHS))

IWORK

          IWORK is INTEGER array, dimension (2*NMAX)

NOUT

          NOUT is INTEGER
          The unit number for output.
