#!N #!N A vector is a quantity that has both magnitude 
and direction in  #!F-adobe-times-medium-i-normal--18*   n #!EF -dimensional space. It corresponds to 
a directed line segment whose length represents the magnitude of the 
vector and whose orientation corresponds to its direction. #!N #!N Vectors 
are composed of a sequence of scalar values enclosed by square 
brackets  #!F-adobe-times-bold-r-normal--18*   [ ] #!EF . The scalar values can be 
separated by commas if desired, although this is not necessary. If 
the elements of a vector are not homogeneous, (e.g., if they 
are both integer and floating-point elements), then the integer elements are 
converted to floating point. The following are all valid vectors: #!N
