```slar2v.f(3)							      LAPACK							       slar2v.f(3)

NAME
slar2v.f -

SYNOPSIS
Functions/Subroutines
subroutine slar2v (N, X, Y, Z, INCX, C, S, INCC)
SLAR2V

Function/Subroutine Documentation
subroutine slar2v (integerN, real, dimension( * )X, real, dimension( * )Y, real, dimension( * )Z, integerINCX, real, dimension( * )C, real,
dimension( * )S, integerINCC)
SLAR2V

Purpose:

SLAR2V applies a vector of real plane rotations from both sides to
a sequence of 2-by-2 real symmetric matrices, defined by the elements
of the vectors x, y and z. For i = 1,2,...,n

( x(i)  z(i) ) := (  c(i)  s(i) ) ( x(i)  z(i) ) ( c(i) -s(i) )
( z(i)  y(i) )	 ( -s(i)  c(i) ) ( z(i)  y(i) ) ( s(i)	c(i) )

Parameters:
N

N is INTEGER
The number of plane rotations to be applied.

X

X is REAL array,
dimension (1+(N-1)*INCX)
The vector x.

Y

Y is REAL array,
dimension (1+(N-1)*INCX)
The vector y.

Z

Z is REAL array,
dimension (1+(N-1)*INCX)
The vector z.

INCX

INCX is INTEGER
The increment between elements of X, Y and Z. INCX > 0.

C

C is REAL array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.

S

S is REAL array, dimension (1+(N-1)*INCC)
The sines of the plane rotations.

INCC

INCC is INTEGER
The increment between elements of C and S. INCC > 0.
