vector \vec"tor\, n. l., a bearer, carrier. fr. vehere, vectum,
   to carry.
   1. same as radius vector.

   2. math. a directed quantity, as a straight line, a force,
      or a velocity. vectors are said to be equal when their
      directions are the same and their magnitudes equal. cf.
      scalar.

   note: in a triangle, either side is the vector sum of the
         other two sides taken in proper order; the process
         finding the vector sum of two or more vectors is vector
         addition see under addition.

vector
     
        1.  a member of a vector space.
     
        2.  a line or movement defined by its end points, or
        by the current position and one other point.  see vector
        graphics.
     
        3.  a memory location containing the address
        of some code, often some kind of exception handler or other
        operating system service.  by changing the vector to point
        to a different piece of code it is possible to modify the
        behaviour of the operating system.
     
        compare hook.
     
        4.  a one-dimensional array.
