SCHKTZ
Purpose:
SCHKTZ tests STZRZF.
- 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 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 (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 REAL array, dimension (MMAX*NMAX)
S
S is REAL array, dimension (min(MMAX,NMAX))
TAU
TAU is REAL array, dimension (MMAX)
WORK
WORK is REAL array, dimension (MMAX*NMAX + 4*NMAX + MMAX)
NOUT
NOUT is INTEGER The unit number for output.
