Function/Subroutine Documentation
subroutine ddrvab (logical, dimension( * ) dotype, integer nm, integer, dimension( * ) mval, integer nns, integer, dimension( * ) nsval, double precision thresh, integer nmax, double precision, dimension( * ) a, double precision, dimension( * ) afac, double precision, dimension( * ) b, double precision, dimension( * ) x, double precision, dimension( * ) work, double precision, dimension( * ) rwork, real, dimension(*) swork, integer, dimension( * ) iwork, integer nout)
DDRVAB
Purpose:
DDRVAB tests DSGESV
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.
NM
NM is INTEGER The number of values of M contained in the vector MVAL.
MVAL
MVAL is INTEGER array, dimension (NM) The values of the matrix row dimension M.
NNS
NNS is INTEGER The number of values of NRHS contained in the vector NSVAL.
NSVAL
NSVAL is INTEGER array, dimension (NNS) The values of the number of right hand sides NRHS.
THRESH
THRESH is DOUBLE PRECISION 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.
NMAX
NMAX is INTEGER The maximum value permitted for M or N, used in dimensioning the work arrays.
A
A is DOUBLE PRECISION array, dimension (NMAX*NMAX)
AFAC
AFAC is DOUBLE PRECISION array, dimension (NMAX*NMAX)
B
B is DOUBLE PRECISION array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
X
X is DOUBLE PRECISION array, dimension (NMAX*NSMAX)
WORK
WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX))
RWORK
RWORK is DOUBLE PRECISION array, dimension (max(2*NMAX,2*NSMAX+NWORK))
SWORK
SWORK is REAL array, dimension (NMAX*(NSMAX+NMAX))
IWORK
IWORK is INTEGER array, dimension NMAX
NOUT
NOUT is INTEGER The unit number for output.
