2 cp - cross product of two 3 element vectors
8 x, y 1-dimensional matrices with 3 elements
10 return 1-dimensional matrix with 3 elements
13 Calculate the product of two 3 1-dimensional matrices.
14 If x has elements (x0, x1, x2), and y has elements (y0, y1, y2),
15 cp(x,y) returns the matrix of type [0:2] with elements:
17 {x1 * y2 - x2 * y1, x3 * y1 - x1 * y3, x1 * y2 - x2 * y1}
24 mat [3] (3 elements, 3 nonzero):
30 The components of the matrices are to be of types for which the
31 required algebraic operations have been defined.
