slarrr.f(3) LAPACK slarrr.f(3)NAME
slarrr.f -
SYNOPSIS
Functions/Subroutines
subroutine slarrr (N, D, E, INFO)
SLARRR
Function/Subroutine Documentation
subroutine slarrr (integerN, real, dimension( * )D, real, dimension( * )E, integerINFO)
SLARRR
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.

Hi Admin,
I am living in singapore. When i use the unix.com in office, it works well ( in that time, it says "you are somewhere around USA(some country) - because my proxy is USA"
Once i come to home and connects, it keeps logout... is that any settings i need to change ?
