Function Documentation
subroutine dlasq6 (integer i0, integer n0, double precision, dimension( * )z, integer pp, double precision dmin, double precision dmin1, doubleprecision dmin2, double precision dn, double precision dnm1, doubleprecision dnm2)
DLASQ6 computes one dqd transform in ping-pong form. Used by sbdsqr and sstegr.
Purpose:
DLASQ6 computes
one dqd (shift equal to zero) transform in
ping-pong form, with protection against underflow and
overflow.
Parameters
I0
I0 is INTEGER

N0
N0 is INTEGER
Last index.
Z
Z is DOUBLE
PRECISION array, dimension ( 4*N )
Z holds the qd array. EMIN is stored in Z(4*N0) to avoid
an extra argument.
PP
PP is INTEGER
PP=0 for ping, PP=1 for pong.
DMIN
DMIN is DOUBLE
PRECISION
Minimum value of d.
DMIN1
DMIN1 is DOUBLE
PRECISION
Minimum value of d, excluding D( N0 ).
DMIN2
DMIN2 is DOUBLE
PRECISION
Minimum value of d, excluding D( N0 ) and D( N0-1 ).
DN
DN is DOUBLE
PRECISION
d(N0), the last value of d.
DNM1
DNM1 is DOUBLE
PRECISION
d(N0-1).
DNM2
DNM2 is DOUBLE
PRECISION
d(N0-2).
