dlasq3
dlasq3.f(3) LAPACK dlasq3.f(3) NAME
dlasq3.f - SYNOPSIS
Functions/Subroutines subroutine dlasq3 (I0, N0, Z, PP, DMIN, SIGMA, DESIG, QMAX, NFAIL, ITER, NDIV, IEEE, TTYPE, DMIN1, DMIN2, DN, DN1, DN2, G, TAU) DLASQ3 Function/Subroutine Documentation subroutine dlasq3 (integerI0, integerN0, double precision, dimension( * )Z, integerPP, double precisionDMIN, double precisionSIGMA, double precisionDESIG, double precisionQMAX, integerNFAIL, integerITER, integerNDIV, logicalIEEE, integerTTYPE, double precisionDMIN1, double precisionDMIN2, double precisionDN, double precisionDN1, double precisionDN2, double precisionG, double precisionTAU) DLASQ3 Purpose: DLASQ3 checks for deflation, computes a shift (TAU) and calls dqds. In case of failure it changes shifts, and tries again until output is positive. 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. PP=2 indicates that flipping was applied to the Z array and that the initial tests for deflation should not be performed. DMIN DMIN is DOUBLE PRECISION Minimum value of d. SIGMA SIGMA is DOUBLE PRECISION Sum of shifts used in current segment. DESIG DESIG is DOUBLE PRECISION Lower order part of SIGMA QMAX QMAX is DOUBLE PRECISION Maximum value of q. NFAIL NFAIL is INTEGER Number of times shift was too big. ITER ITER is INTEGER Number of iterations. NDIV NDIV is INTEGER Number of divisions. IEEE IEEE is LOGICAL Flag for IEEE or non IEEE arithmetic (passed to DLASQ5). TTYPE TTYPE is INTEGER Shift type. DMIN1 DMIN1 is DOUBLE PRECISION DMIN2 DMIN2 is DOUBLE PRECISION DN DN is DOUBLE PRECISION DN1 DN1 is DOUBLE PRECISION DN2 DN2 is DOUBLE PRECISION G G is DOUBLE PRECISION TAU TAU is DOUBLE PRECISION These are passed as arguments in order to save their values between calls to DLASQ3.
