Computes the hard clustering through the Maximum A Posteriori rule from the matrix of a posteriori probabilities (soft clustering).

`tau` |
matrix with posterior probabilities of each class for each observation (classes in columns, observations in rows). |

`n` |
number of observations. |

`K` |
number of classes. |

a matrix of same dimensions as *tau*. For each observation (row), only zeros except for the column corresponding to the cluster to which the observation is assigned, which value is one.
