CSROT

Function/Subroutine Documentation

  subroutine csrot (integer n, complex, dimension( * ) cx, integer incx, complex, dimension( * ) cy, integer incy, real c, real s)

CSROT

Purpose:

    !>
    !> CSROT applies a plane rotation, where the cos and sin (c and s) are real
    !> and the vectors cx and cy are complex.

Parameters
    N

    !>          N is INTEGER
    !>           On entry, N specifies the order of the vectors cx and cy.
    !>           N must be at least zero.
    !>

    CX

    !>          CX is COMPLEX array, dimension at least
    !>           ( 1 + ( N - 1 )*abs( INCX ) ).
    !>           Before entry, the incremented array CX must contain the n
    !>           element vector cx. On exit, CX is overwritten by the updated
    !>           vector cx.
    !>

    INCX

    !>          INCX is INTEGER
    !>           On entry, INCX specifies the increment for the elements of
    !>           CX. INCX must not be zero.
    !>

    CY

    !>          CY is COMPLEX array, dimension at least
    !>           ( 1 + ( N - 1 )*abs( INCY ) ).
    !>           Before entry, the incremented array CY must contain the n
    !>           element vector cy. On exit, CY is overwritten by the updated
    !>           vector cy.
    !>

    INCY

    !>          INCY is INTEGER
    !>           On entry, INCY specifies the increment for the elements of
    !>           CY. INCY must not be zero.
    !>

    C

    !>          C is REAL
    !>           On entry, C specifies the cosine, cos.
    !>

    S

    !>          S is REAL
    !>           On entry, S specifies the sine, sin.
