SCHKQ3

Purpose:

 SCHKQ3 tests SGEQP3.

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.

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.

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)

IWORK

          IWORK is INTEGER array, dimension (2*NMAX)

NOUT

          NOUT is INTEGER
          The unit number for output.
