!> DCKCSD tests DORCSD:
!>        the CSD for an M-by-M orthogonal matrix X partitioned as
!>        [ X11 X12; X21 X22 ]. X11 is P-by-Q.
!> 

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.
!> 

PVAL

!>          PVAL is INTEGER array, dimension (NM)
!>          The values of the matrix row dimension P.
!> 

QVAL

!>          QVAL is INTEGER array, dimension (NM)
!>          The values of the matrix column dimension Q.
!> 

NMATS

!>          NMATS is INTEGER
!>          The number of matrix types to be tested for each combination
!>          of matrix dimensions.  If NMATS >= NTYPES (the maximum
!>          number of matrix types), then all the different types are
!>          generated for testing.  If NMATS < NTYPES, another input line
!>          is read to get the numbers of the matrix types to be used.
!> 

ISEED

!>          ISEED is INTEGER array, dimension (4)
!>          On entry, the seed of the random number generator.  The array
!>          elements should be between 0 and 4095, otherwise they will be
!>          reduced mod 4096, and ISEED(4) must be odd.
!>          On exit, the next seed in the random number sequence after
!>          all the test matrices have been generated.
!> 

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.
!> 

MMAX

!>          MMAX is INTEGER
!>          The maximum value permitted for M, used in dimensioning the
!>          work arrays.
!> 

X

!>          X is DOUBLE PRECISION array, dimension (MMAX*MMAX)
!> 

XF

!>          XF is DOUBLE PRECISION array, dimension (MMAX*MMAX)
!> 

U1

!>          U1 is DOUBLE PRECISION array, dimension (MMAX*MMAX)
!> 

U2

!>          U2 is DOUBLE PRECISION array, dimension (MMAX*MMAX)
!> 

V1T

!>          V1T is DOUBLE PRECISION array, dimension (MMAX*MMAX)
!> 

V2T

!>          V2T is DOUBLE PRECISION array, dimension (MMAX*MMAX)
!> 

THETA

!>          THETA is DOUBLE PRECISION array, dimension (MMAX)
!> 

IWORK

!>          IWORK is INTEGER array, dimension (MMAX)
!> 

WORK

!>          WORK is DOUBLE PRECISION array
!> 

RWORK

!>          RWORK is DOUBLE PRECISION array
!> 

NIN

!>          NIN is INTEGER
!>          The unit number for input.
!> 

NOUT

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

INFO

!>          INFO is INTEGER
!>          = 0 :  successful exit
!>          > 0 :  If DLAROR returns an error code, the absolute value
!>                 of it is returned.
