NAME¶
/home/abuild/rpmbuild/BUILD/lapack-3.12.0/TESTING/EIG/cget36.f
SYNOPSIS¶
Functions/Subroutines¶
subroutine CGET36 (rmax, lmax, ninfo, knt, nin)
CGET36
Function/Subroutine Documentation¶
subroutine CGET36 (real rmax, integer lmax, integer ninfo, integer knt, integer nin)¶
CGET36
Purpose:
!> !> CGET36 tests CTREXC, a routine for reordering diagonal entries of a !> matrix in complex Schur form. Thus, CLAEXC computes a unitary matrix !> Q such that !> !> Q' * T1 * Q = T2 !> !> and where one of the diagonal blocks of T1 (the one at row IFST) has !> been moved to position ILST. !> !> The test code verifies that the residual Q'*T1*Q-T2 is small, that T2 !> is in Schur form, and that the final position of the IFST block is !> ILST. !> !> The test matrices are read from a file with logical unit number NIN. !>
Parameters
RMAX
!> RMAX is REAL !> Value of the largest test ratio. !>
LMAX
!> LMAX is INTEGER !> Example number where largest test ratio achieved. !>
NINFO
!> NINFO is INTEGER !> Number of examples where INFO is nonzero. !>
KNT
!> KNT is INTEGER !> Total number of examples tested. !>
NIN
!> NIN is INTEGER !> Input logical unit number. !>
