/sys$common/syshlp/helplib.hlb FORTRAN, Intrinsic Procedures, xZAXPY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  SZAXPY (n, a, x, incx, y, incy, z, incz)
  DZAXPY (n, a, x, incx, y, incy, z, incz)
  CZAXPY (n, a, x, incx, y, incy, z, incz)
  ZZAXPY (n, a, x, incx, y, incy, z, incz)

  Subroutines that multiply an array "x" by a scalar "a" and add an
  array "y"; the result is stored in a third array "z".

  These routines are part of the BLAS1 Extended Set, and are
  available only on VAX processors.  The Compaq Extended Math
  Library product may be needed to resolve references to Extended Set
  routines that are not expanded inline by the compiler.

  Arguments

    n

    Integer number of elements in arrays "x", "y" and "z" to be
    accessed.

    a

    Scalar multiplier for array x.  The data type is REAL*4 for
    SZAXPY, REAL*8 for DZAXPY, COMPLEX*8 for CZAXPY, COMPLEX*16 for
    ZZAXPY.

    x

    Array containing the elements to be accessed or array reference
    to the first such element.  The data type is REAL*4 for SZAXPY,
    REAL*8 for DZAXPY, COMPLEX*8 for CZAXPY, COMPLEX*16 for ZZAXPY.
    The elements in array "x" are multiplied by the scalar argument
    "a" and then added to elements of array "y"; the results are
    stored in array "z".

    incx

    Integer index increment used in selecting which elements of array
    "x" are accessed.

    y

    Array containing the elements to be accessed or array reference
    to the first such element.  The data type is REAL*4 for SZAXPY,
    REAL*8 for DZAXPY, COMPLEX*8 for CZAXPY, COMPLEX*16 for ZZAXPY.
    The elements of array "y" are added to the product of scalar "a"
    and array "x"; the result is stored in array "z".

    incy

    Integer index increment used in selecting which elements of array
    "y" are accessed.

    z

    Array containing the elements to receive the result values or
    array reference to the first such element.  The data type is
    REAL*4 for SZAXPY, REAL*8 for DZAXPY, COMPLEX*8 for CZAXPY,
    COMPLEX*16 for ZZAXPY.

    incz

    Integer index increment used in selecting which elements of array
    "z" are accessed.
