Vectors

To compute usual vectorial operations, use the symbols: (, ), +, -, * (multiplication by a number or scalar product of two vectors), / (division by a number).

Here are all the vector valued functions:

• vector(x, y)
  Vector of abscissa x and ordinate y.
• vector(x, a)
  Vector of length x and argument a.
• vector(A, B)
  Vector from point A to point B.
• vector(l)
  Unit length vector with same direction than line l.
• vector(s)
  Vector from begin of segment s to end of s.
• rotation(u, a)
