SYNOPSIS
Functions/Subroutines subroutine dlasq4 (I0, N0, Z, PP, N0IN, DMIN, DMIN1, DMIN2, DN, DN1, DN2, TAU, TTYPE, G) DLASQ4 computes an approximation to the smallest eigenvalue using values of d from the previous transform. Used by sbdsqr. Function/Subroutine Documentation subroutine dlasq4 (integerI0, integerN0, double precision, dimension( * )Z, integerPP, integerN0IN, double precisionDMIN, double precisionDMIN1, double precisionDMIN2, double precisionDN, double precisionDN1, double precisionDN2, double precisionTAU, integerTTYPE, double precisionG) DLASQ4 computes an approximation to the smallest eigenvalue using values of d from the previous transform. Used by sbdsqr. Purpose: DLASQ4 computes an approximation TAU to the smallest eigenvalue using values of d from the previous transform. Parameters: I0 I0 is INTEGER First index. N0 N0 is INTEGER Last index. Z Z is DOUBLE PRECISION array, dimension ( 4*N ) Z holds the qd array. PP PP is INTEGER PP=0 for ping, PP=1 for pong. N0IN N0IN is INTEGER The value of N0 at start of EIGTEST. 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(N) DN1 DN1 is DOUBLE PRECISION d(N-1) DN2 DN2 is DOUBLE PRECISION d(N-2) TAU TAU is DOUBLE PRECISION This is the shift. TTYPE TTYPE is INTEGER Shift type. G G is REAL G is passed as an argument in order to save its value between calls to DLASQ4. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
