This function generates *d* dependent (homogeneous or nonhomogeneous) point processes
using a marked PP, where the marks are generated by a Markov chain process defined by a given transition matrix.

1 | ```
DepMarkedNHPP.fun(lambdaTot, MarkovM, inival = 1, fixed.seed=NULL)
``` |

`lambdaTot` |
Numeric vector. Intensity values of the underlying PP used to generate the dependent processes. |

`MarkovM` |
Matrix. Trasition probabilities of the d-state Markov chain used to generate the marks of the PP. |

`inival` |
Optional. Initial mark value used to generate the series of marks. |

`fixed.seed` |
Optional. An integer or NULL. Value used to set the seed in random generation processes; if it is NULL, a random seed is used. |

Points of the marked PP are generated in continuous time, using the following procedure: First, a trajectory of the underlying PP, which represents the global process of the occurrences in all the processes, is generated. Then, the mark series is generated using a d-state Markov chain. The mark series takes values in 1,2,...,d and determines in which of the d processes the point occurs

A transition matrix *P = (p_{ij})* with
equal rows leads to d independent point processes, and the more similar the rows of P, the less dependent the
resulting processes. Some dependence measures between the generated processes, such as the spectral gap,
are suggested in Abaurrea et al. (2014).

It is noteworthy, that the processes defined by the marks are not Poisson, since the generated marks are dependent observations, see Isham (1980).
