SCHKLQ

Purpose:

!>
!> SCHKLQ tests SGELQF, SORGLQ and SORMLQ.
!>

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.
!>

NNB

!>          NNB is INTEGER
!>          The number of values of NB and NX contained in the
!>          vectors NBVAL and NXVAL.  The blocking parameters are used
!>          in pairs (NB,NX).
!>

NBVAL

!>          NBVAL is INTEGER array, dimension (NNB)
!>          The values of the blocksize NB.
!>

NXVAL

!>          NXVAL is INTEGER array, dimension (NNB)
!>          The values of the crossover point NX.
!>

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 M or N, used in dimensioning
!>          the work arrays.
!>

A

!>          A is REAL array, dimension (NMAX*NMAX)
!>

AF

!>          AF is REAL array, dimension (NMAX*NMAX)
!>

AQ

!>          AQ is REAL array, dimension (NMAX*NMAX)
!>

AL

!>          AL is REAL array, dimension (NMAX*NMAX)
!>

AC

!>          AC is REAL array, dimension (NMAX*NMAX)
!>

B

!>          B is REAL array, dimension (NMAX*NRHS)
!>

X

!>          X is REAL array, dimension (NMAX*NRHS)
!>

XACT

!>          XACT is REAL array, dimension (NMAX*NRHS)
!>

TAU

!>          TAU is REAL array, dimension (NMAX)
!>

WORK

!>          WORK is REAL array, dimension (NMAX*NMAX)
!>

RWORK

!>          RWORK is REAL array, dimension (NMAX)
!>

NOUT

!>          NOUT is INTEGER
!>          The unit number for output.
