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 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 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 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 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.
