slartgp.f
slartgp.f(3) LAPACK slartgp.f(3)
NAME
slartgp.f -
SYNOPSIS
Functions/Subroutines
subroutine slartgp (F, G, CS, SN, R)
SLARTGP
Function/Subroutine Documentation
subroutine slartgp (realF, realG, realCS, realSN, realR)
SLARTGP
Purpose:
SLARTGP generates a plane rotation so that
[ CS SN ] . [ F ] = [ R ] where CS**2 + SN**2 = 1.
[ -SN CS ] [ G ] [ 0 ]
This is a slower, more accurate version of the Level 1 BLAS routine SROTG,
with the following other differences:
F and G are unchanged on return.
If G=0, then CS=(+/-)1 and SN=0.
If F=0 and (G .ne. 0), then CS=0 and SN=(+/-)1.
The sign is chosen so that R >= 0.
Parameters:
F
F is REAL
The first component of vector to be rotated.
G
G is REAL
The second component of vector to be rotated.
CS
CS is REAL
The cosine of the rotation.
SN
SN is REAL
The sine of the rotation.
R
R is REAL
The nonzero component of the rotated vector.
