void largv(integer *n, T *x, integer *incx, T *y, integer *incy, T *c, integer *incc)# LARGV generates a vector of plane rotations with real cosines and real sines.
Purpose:
LARGV 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 – [in]
N is INTEGER
The number of plane rotations to be generated.
X – [inout]
X is REAL array, dimension (1+(N-1)*INCX)
On entry, the vector x. On exit, x(i) is overwritten by a(i), for i = 1,…,n.
INCX – [in]
INCX is INTEGER
The increment between elements of X. INCX > 0.
Y – [inout]
Y is REAL array, dimension (1+(N-1)*INCY)
On entry, the vector y. On exit, the sines of the plane rotations.
INCY – [in]
INCY is INTEGER
The increment between elements of Y. INCY > 0.
C – [out]
C is REAL array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.
INCC – [in]
INCC is INTEGER
The increment between elements of C. INCC > 0.
