NAME¶
/home/abuild/rpmbuild/BUILD/lapack-3.12.0/TESTING/EIG/cget35.f
SYNOPSIS¶
Functions/Subroutines¶
subroutine CGET35 (rmax, lmax, ninfo, knt, nin)
CGET35
Function/Subroutine Documentation¶
subroutine CGET35 (real rmax, integer lmax, integer ninfo, integer knt, integer nin)¶
CGET35
Purpose:
!> !> CGET35 tests CTRSYL, a routine for solving the Sylvester matrix !> equation !> !> op(A)*X + ISGN*X*op(B) = scale*C, !> !> A and B are assumed to be in Schur canonical form, op() represents an !> optional transpose, and ISGN can be -1 or +1. Scale is an output !> less than or equal to 1, chosen to avoid overflow in X. !> !> The test code verifies that the following residual is order 1: !> !> norm(op(A)*X + ISGN*X*op(B) - scale*C) / !> (EPS*max(norm(A),norm(B))*norm(X)) !>
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. !>
