CSROT(3F)CSROT(3F)NAMECSROT - CSROT applies the complex Givens rotation
(X) ( C S)(X)
(Y) = (-S C)(Y)
N times where for I = 0,...,N-1
X = CX(1+I*INCX)
Y = CY(1+I*INCY)
SYNOPSYS
SUBROUTINE CSROT(N,CX,INCX,CY,INCY,C,S)
DESCRIPTION
Argument Description
N (integer) number of elements in each vector
CX (complex array) beginning of one vector
INCX (integer) memory spacing of successive elements
of vector CX
CY (complex array) beginning of the other vector
INCY (integer) memory spacing of successive elements
of vector CY
C (real) cosine term of the rotation
S (real) sine term of the rotation.
