SLARGV generates a vector of plane rotations with real cosines and real sines.
Function/Subroutine Documentation
subroutine slargv (integerN, real, dimension( * )X, integerINCX, real, dimension( * )Y,
integerINCY, real, dimension( * )C, integerINCC)
SLARGV generates a vector of plane rotations with real cosines and real sines.
Purpose:
SLARGV generates a vector of real plane rotations, determined by
elements of the real vectors x and y. For i = 1,2,...,n
( c(i) s(i) ) ( x(i) ) = ( a(i) )
( s(i) c(i) ) ( y(i) ) = ( 0 )
Parameters:
N
N is INTEGER
The number of plane rotations to be generated.
X
X is REAL array,
dimension (1+(N1)*INCX)
On entry, the vector x.
On exit, x(i) is overwritten by a(i), for i = 1,...,n.
INCX
INCX is INTEGER
The increment between elements of X. INCX > 0.
Y
Y is REAL array,
dimension (1+(N1)*INCY)
On entry, the vector y.
On exit, the sines of the plane rotations.
INCY
INCY is INTEGER
The increment between elements of Y. INCY > 0.
C
C is REAL array, dimension (1+(N1)*INCC)
The cosines of the plane rotations.
INCC
INCC is INTEGER
The increment between elements of C. INCC > 0.
