subroutine sget34 (rmax, lmax, ninfo, knt)
SGET34
SGET34
Purpose:
SGET34 tests SLAEXC, a routine for swapping adjacent blocks (either
1 by 1 or 2 by 2) on the diagonal of a matrix in real Schur form.
Thus, SLAEXC computes an orthogonal matrix Q such that
Q' * [ A B ] * Q = [ C1 B1 ]
[ 0 C ] [ 0 A1 ]
where C1 is similar to C and A1 is similar to A. Both A and C are
assumed to be in standard form (equal diagonal entries and
offdiagonal with differing signs) and A1 and C1 are returned with the
same properties.
The test code verifies these last last assertions, as well as that
the residual in the above equation is small.
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 array, dimension (2)
NINFO(J) is the number of examples where INFO=J occurred.
KNT
KNT is INTEGER
Total number of examples tested.
