Function/Subroutine Documentation

  subroutine zscal (integer N, complex*16 ZA, complex*16, dimension(*) ZX, integer INCX)

ZSCAL

Purpose:

        ZSCAL scales a vector by a constant.

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
