subroutineclacrt(integern,complex,dimension(*)cx,integerincx,complex,dimension(*)cy,integerincy,complexc,complexs)CLACRT performs a linear transformation of a pair of complex vectors. Purpose: CLACRT performs the operation ( c s )( x ) ==> ( x ) ( -s c )( y ) ( y ) where c and s are complex and the vectors x and y are complex. ParametersN N is INTEGER The number of elements in the vectors CX and CY. CX CX is COMPLEX array, dimension (N) On input, the vector x. On output, CX is overwritten with c*x + s*y. INCX INCX is INTEGER The increment between successive values of CX. INCX <> 0. CY CY is COMPLEX array, dimension (N) On input, the vector y. On output, CY is overwritten with -s*x + c*y. INCY INCY is INTEGER The increment between successive values of CY. INCY <> 0. C C is COMPLEX S S is COMPLEX C and S define the matrix [ C S ].
