The KOffice 2.0 beta, part 2: Graphical and charting programs
10-10-2008 08:00 AM
Yesterday, I looked at the major applications in the first beta for KOffice 2.0. Now it's the turn of the rest of the beta: The KPlato project manager, KChart, the vector graphics editor Karbon, and the raster graphics editor Krita.
Hey guys,
Suppose i run passwd via bash shell. It is a suid program, which temporarily runs as root(owner) and modifies the user entries.
However, when i write a C file and give 4755 permission and root ownership to the 'a.out' file , it doesn't run as root in bash shell. I verified this by... (2 Replies)
Are the programs written on schedulers ,thread library , process management, memory management, et al called systems programs ? How are they different from the programs that implement functions like open() , printf() , scanf() , read() .. they have a prefix sys_open, sys_close, sys_read etc , right... (1 Reply)

SYNOPSIS
Functions/Subroutines
subroutine dlarfgp (N, ALPHA, X, INCX, TAU)
DLARFGP generates an elementary reflector (Householder matrix) with non-negatibe beta.
Function/Subroutine Documentation
subroutine dlarfgp (integerN, double precisionALPHA, double precision, dimension( * )X, integerINCX, double precisionTAU)
DLARFGP generates an elementary reflector (Householder matrix) with non-negatibe beta.
Purpose:
DLARFGP generates a real elementary reflector H of order n, such
that
H * ( alpha ) = ( beta ), H**T * H = I.
( x ) ( 0 )
where alpha and beta are scalars, beta is non-negative, and x is
an (n-1)-element real vector. H is represented in the form
H = I - tau * ( 1 ) * ( 1 v**T ) ,
( v )
where tau is a real scalar and v is a real (n-1)-element
vector.
If the elements of x are all zero, then tau = 0 and H is taken to be
the unit matrix.
Parameters:
N
N is INTEGER
The order of the elementary reflector.
ALPHA
ALPHA is DOUBLE PRECISION
On entry, the value alpha.
On exit, it is overwritten with the value beta.
X
X is DOUBLE PRECISION array, dimension
(1+(N-2)*abs(INCX))
On entry, the vector x.
On exit, it is overwritten with the vector v.
INCX
INCX is INTEGER
The increment between elements of X. INCX > 0.
TAU
TAU is DOUBLE PRECISION
The value tau.
