An vector of orientations, each represented by a vector of numbers.
Each of these types stores orientations as rows of a matrix in slot
eulerzyx class uses 3 Euler angles in the roll-pitch-yaw scheme
(rotation about Z axis, then Y axis, then X axis).
eulerzxz class uses 3 Euler angles in the X system scheme
(rotation about Z axis, then X axis, then Z axis again).
rotvector class uses the 9 components of a 3 x 3 rotation matrix, stored
in column-major order.
quaternion class uses the 4 components of a unit quaternion.
skewvector class uses the 3 non-zero components of a skew-symmetric matrix,
(x,y,z) stores the matrix
((0, -z, y), (z, 0, -x), (-y, x, 0)).
Objects of each class can be created by calls to the corresponding constructor
An n x m
matrix object holding the vector representations, where
m is 3, 4, or 9.
