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.
