slasq3.f
slasq3.f(3) LAPACK slasq3.f(3) NAME
slasq3.f - SYNOPSIS
Functions/Subroutines subroutine slasq3 (I0, N0, Z, PP, DMIN, SIGMA, DESIG, QMAX, NFAIL, ITER, NDIV, IEEE, TTYPE, DMIN1, DMIN2, DN, DN1, DN2, G, TAU) SLASQ3 Function/Subroutine Documentation subroutine slasq3 (integerI0, integerN0, real, dimension( * )Z, integerPP, realDMIN, realSIGMA, realDESIG, realQMAX, integerNFAIL, integerITER, integerNDIV, logicalIEEE, integerTTYPE, realDMIN1, realDMIN2, realDN, realDN1, realDN2, realG, realTAU) SLASQ3 Purpose: SLASQ3 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 REAL 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 REAL Minimum value of d. SIGMA SIGMA is REAL Sum of shifts used in current segment. DESIG DESIG is REAL Lower order part of SIGMA QMAX QMAX is REAL 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 SLASQ5). TTYPE TTYPE is INTEGER Shift type. DMIN1 DMIN1 is REAL DMIN2 DMIN2 is REAL DN DN is REAL DN1 DN1 is REAL DN2 DN2 is REAL G G is REAL TAU TAU is REAL These are passed as arguments in order to save their values between calls to SLASQ3.
