NAME
slasq6.f -
SYNOPSIS
Functions/Subroutines subroutine slasq6 (I0, N0, Z, PP, DMIN, DMIN1, DMIN2, DN, DNM1, DNM2) SLASQ6 computes one dqd transform in ping-pong form. Used by sbdsqr and sstegr. Function/Subroutine Documentation subroutine slasq6 (integerI0, integerN0, real, dimension( * )Z, integerPP, realDMIN, realDMIN1, realDMIN2, realDN, realDNM1, realDNM2) SLASQ6 computes one dqd transform in ping-pong form. Used by sbdsqr and sstegr. Purpose: SLASQ6 computes one dqd (shift equal to zero) transform in ping-pong form, with protection against underflow and overflow. Parameters: I0 I0 is INTEGER First index. N0 N0 is INTEGER Last index. Z Z is REAL 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 REAL Minimum value of d. DMIN1 DMIN1 is REAL Minimum value of d, excluding D( N0 ). DMIN2 DMIN2 is REAL Minimum value of d, excluding D( N0 ) and D( N0-1 ). DN DN is REAL d(N0), the last value of d. DNM1 DNM1 is REAL d(N0-1). DNM2 DNM2 is REAL d(N0-2).
