SCHKPP
Purpose:
!> !> SCHKPP tests SPPTRF, -TRI, -TRS, -RFS, and -CON !>
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. !>
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 dimension N. !>
NNS
!> NNS is INTEGER !> The number of values of NRHS contained in the vector NSVAL. !>
NSVAL
!> NSVAL is INTEGER array, dimension (NNS) !> The values of the number of right hand sides NRHS. !>
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 N, used in dimensioning the !> work arrays. !>
A
!> A is REAL array, dimension !> (NMAX*(NMAX+1)/2) !>
AFAC
!> AFAC is REAL array, dimension !> (NMAX*(NMAX+1)/2) !>
AINV
!> AINV is REAL array, dimension !> (NMAX*(NMAX+1)/2) !>
B
!> B is REAL array, dimension (NMAX*NSMAX) !> where NSMAX is the largest entry in NSVAL. !>
X
!> X is REAL array, dimension (NMAX*NSMAX) !>
XACT
!> XACT is REAL array, dimension (NMAX*NSMAX) !>
WORK
!> WORK is REAL array, dimension !> (NMAX*max(3,NSMAX)) !>
RWORK
!> RWORK is REAL array, dimension !> (max(NMAX,2*NSMAX)) !>
IWORK
!> IWORK is INTEGER array, dimension (NMAX) !>
NOUT
!> NOUT is INTEGER !> The unit number for output. !>
