#' @description
#' This packages proposes a model-based clustering algorithm for multivariate functional data.
#' The parametric mixture model, based on the assumption of normality of the principal components resulting from a multivariate functional PCA, is estimated by an EM-like algorithm.
#' The main advantage of the proposed algorithm is its ability to take into account the dependence among curves.
#'
#' @details
#' This package included a function named \link{funclust} which allow to perform functional data clustering.
#' This package allows also to perform a functional PCA (function \link{mfpca}) for univariate or multivariate functional data, with possibility to define different weights for each observation.
#' The output of funclust and mfpca are a list, so one can use summary() to display the results.
#' We can also plot the original curves with function \link{plotOC}. The function \link{plotfd} plots the curves after interpolation or smoothing.
#' See the help of theses functions for more details.
