| − | Converts angle-axis rotation parameters into a quaternion.
| |
| − | | |
| − | ==Syntax==
| |
| − | | |
| − | q=anax2quat(rot_axis,rot_angle)
| |
| − | | |
| − | ==Parameters==
| |
| − | | |
| − | rot_axis - cartesian direction vector given as a
| |
| − | row or column with three real elements
| |
| − |
| |
| − | rot_angle - rotation angle in radians
| |
| − | | |
| − | ==Outputs==
| |
| − | | |
| − | q - a structure with four fields q.u, q.i,
| |
| − | q.j, q.k giving the four components of
| |
| − | the quaternion
| |
| − | | |
| − | ==Notes==
| |
| − | Both angle-axis and quaternion convention are numerically stable. This conversion has no singularities. See the notes on [[rotation conventions]] for the basic definitions of rotations in ''Spinach''.
