Variance covariance matrix of the values at the tips of a tree under an OU process

1 2 |

`tree` |
A phylo object. |

`alpha, sigma` |
Non-negative numeric values, parameters of the OU process. |

`sigmae` |
Non-negative numeric value, environmental standard deviation at the tips. |

`tanc` |
Numerical matrix with the time-distance from the root of the tree to the mrca of each tip-couple. If NULL it will be calculated. |

`tauij` |
Numerical matrix with the time (patristic) distance between each pair of tips. If NULL, it will be calculated. |

`corr` |
Logical indicating if a correlation matrix shall be returned. |

a variance covariance or a correlation matrix of the tips in tree.
