Function/Subroutine Documentation
subroutine dchktz (logical, dimension( * ) dotype, integer nm, integer, dimension( * ) mval, integer nn, integer, dimension( * ) nval, double precision thresh, logical tsterr, double precision, dimension( * ) a, double precision, dimension( * ) copya, double precision, dimension( * ) s, double precision, dimension( * ) tau, double precision, dimension( * ) work, integer nout)
DCHKTZ
Purpose:
DCHKTZ tests DTZRZF.
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.
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 column dimension N.
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.
TSTERR
TSTERR is LOGICAL Flag that indicates whether error exits are to be tested.
A
A is DOUBLE PRECISION array, dimension (MMAX*NMAX) where MMAX is the maximum value of M in MVAL and NMAX is the maximum value of N in NVAL.
COPYA
COPYA is DOUBLE PRECISION array, dimension (MMAX*NMAX)
S
S is DOUBLE PRECISION array, dimension (min(MMAX,NMAX))
TAU
TAU is DOUBLE PRECISION array, dimension (MMAX)
WORK
WORK is DOUBLE PRECISION array, dimension (MMAX*NMAX + 4*NMAX + MMAX)
NOUT
NOUT is INTEGER The unit number for output.
