   Absolute Zero Multiply of valvectors
   ####################################

   Syntax
   ******
   | *z* = ``CppAD::azmul`` ( *x* , *y* )

   x
   *
   The argument *x* is a ``const`` valvector that is passed by reference.

   y
   *
   The argument *y* is a ``const`` valvector that is passed by reference.
   If the size of *x* is not one,
   and the size of *y* is not one,
   the size of *x* and *y* must be equal.

   z
   *
   In the special where all the elements of *z* are zero,
   the result *z* is a valvector with size one.
   Otherwise, *z* is a valvector with size equal to the maximum of the
   size of *x* and the size of *y* .
