Purpose:



 SDRVSY tests the driver routines SSYSV 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 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 side vectors to be generated for


          each linear system.

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.

NMAX



          NMAX is INTEGER


          The maximum value permitted for N, used in dimensioning the


          work arrays.



          A is REAL array, dimension (NMAX*NMAX)

AFAC



          AFAC is REAL array, dimension (NMAX*NMAX)

AINV



          AINV is REAL array, dimension (NMAX*NMAX)



          B is REAL array, dimension (NMAX*NRHS)



          X is REAL array, dimension (NMAX*NRHS)

XACT



          XACT is REAL array, dimension (NMAX*NRHS)

WORK



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

RWORK



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

IWORK



          IWORK is INTEGER array, dimension (2*NMAX)

NOUT



          NOUT is INTEGER


          The unit number for output.
