🦋 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 💜

Here's the full glow-up signature, bestie:

subroutine slasq6 (integer i0, integer n0, real, dimension( * ) z, integer pp, real dmin, real dmin1, real dmin2, real dn, real dnm1, real dnm2)

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