Habeck's rotation matrix generation | R Documentation |

It generates random rotations in three-dimensional space that follow a probability distribution, matrix Fisher distribution, arising in fitting and matching problem.

habeck.rot(F)

`F` |
An arbitrary 3 x 3 matrix represents the parameter matrix of this distribution. |

Firstly rotation matrices **X** are chosen which are the closest to F, and then parameterized using euler angles.
Then a Gibbs sampling algorithm is implemented to generate rotation matrices from the resulting disribution of
the euler angles.
