List of all members.

Public Member Functions
	vec (real c=0)
	Default: initialize to (0,0,0). Note that vec(1) is (1,1,1).
	vec (real x, real y, real z)
	Initialize to (x,y,z).
real &	operator[] (int i)
	Element access.
void	print ()
	Print to cout. Note that cout << vec alwo works.
vec	operator- ()
	Unary -.
real	operator * (const vec &b)
	Dot product.
vec	operator^ (const vec &b)
	Outer product.

Detailed Description

vec: A class for 3-dimensional vectors.

version 1: Dec 1992 Piet Hut, Steve McMillan, Jun Makino
version 2: Jun 2003 Steve McMillan: vector now vec to avoid conflict with upstart STL vector type.

real& vec::operator[] (  int  i  )  [inline]

Element access. []: Allow array-style access. The return type is declared as a reference (&), so that it can be used on the left-hand side of an asignment, as well as on the right-hand side, i.e.v[1] = 3.14 and x = v[2] are both allowed and work as expected.
