Function/Subroutine Documentation

subroutine zaxpy (integer N, complex*16 ZA, complex*16, dimension(*) ZX, integer INCX, complex*16, dimension(*) ZY, integer INCY)

ZAXPY

Purpose: 



    ZAXPY constant times a vector plus a vector.

Parameters:

N 



          N is INTEGER


         number of elements in input vector(s)

ZA



          ZA is COMPLEX*16


           On entry, ZA specifies the scalar alpha.

ZX



          ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) )

INCX



          INCX is INTEGER


         storage spacing between elements of ZX

ZY



          ZY is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCY ) )

INCY



          INCY is INTEGER


         storage spacing between elements of ZY
