SDRVSY

Purpose:

 SDRVSY tests the driver routines SSYSV and -SVX.

Parameters

[in]	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.
[in]	NN	NN is INTEGER The number of values of N contained in the vector NVAL.
[in]	NVAL	NVAL is INTEGER array, dimension (NN) The values of the matrix dimension N.
[in]	NRHS	NRHS is INTEGER The number of right hand side vectors to be generated for each linear system.
[in]	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.
[in]	TSTERR	TSTERR is LOGICAL Flag that indicates whether error exits are to be tested.
[in]	NMAX	NMAX is INTEGER The maximum value permitted for N, used in dimensioning the work arrays.
[out]	A	A is REAL array, dimension (NMAX*NMAX)
[out]	AFAC	AFAC is REAL array, dimension (NMAX*NMAX)
[out]	AINV	AINV is REAL array, dimension (NMAX*NMAX)
[out]	B	B is REAL array, dimension (NMAX*NRHS)
[out]	X	X is REAL array, dimension (NMAX*NRHS)
[out]	XACT	XACT is REAL array, dimension (NMAX*NRHS)
[out]	WORK	WORK is REAL array, dimension (NMAX*max(2,NRHS))
[out]	RWORK	RWORK is REAL array, dimension (NMAX+2*NRHS)
[out]	IWORK	IWORK is INTEGER array, dimension (2*NMAX)
[in]	NOUT	NOUT is INTEGER The unit number for output.
