slarrr.f(3) LAPACK slarrr.f(3) NAME
slarrr.f - SYNOPSIS
Functions/Subroutines subroutine slarrr (N, D, E, INFO) SLARRR performs tests to decide whether the symmetric tridiagonal matrix T warrants expensive computations which guarantee high relative accuracy in the eigenvalues. Function/Subroutine Documentation subroutine slarrr (integerN, real, dimension( * )D, real, dimension( * )E, integerINFO) SLARRR performs tests to decide whether the symmetric tridiagonal matrix T warrants expensive computations which guarantee high relative accuracy in the eigenvalues. Purpose: Perform tests to decide whether the symmetric tridiagonal matrix T warrants expensive computations which guarantee high relative accuracy in the eigenvalues. Parameters: N N is INTEGER The order of the matrix. N > 0. D D is REAL array, dimension (N) The N diagonal elements of the tridiagonal matrix T. E E is REAL array, dimension (N) On entry, the first (N-1) entries contain the subdiagonal elements of the tridiagonal matrix T; E(N) is set to ZERO. INFO INFO is INTEGER INFO = 0(default) : the matrix warrants computations preserving relative accuracy. INFO = 1 : the matrix warrants computations guaranteeing only absolute accuracy.
