\alias{MuChPoint}

\title{MuChPoint fitting procedure}

\usage{

MuChPoint(Y, Lmax = nrow(Y)/2, N = NULL, cores = 1, verbose = TRUE)

}

\arguments{

\item{Y}{symmetric matrix of observations.}

\item{Lmax}{a positive integer less than number of columns (and number of rows).

By default, \code{nrow(Y)/2}.}

\item{N}{a positive integer vector less than number of columns (and number of rows).

N is used when the break-points are known.

By default, \code{NULL}.}

\item{cores}{a positive integer giving the number of cores used. If you use windows,

the parallelization is impossible.

By default, 1.}

\item{verbose}{logical. To display the progression bars. By default TRUE.}

}

\description{

Produce a block-wise estimation of a symmetric matrix.

}

\examples{

require(MuChPoint)

mu=c(rep(c(rep(1,25),rep(0,25)),3))\%*\%t(rep(c(rep(0,25),rep(1,25)),3))

Y=matrix(rnorm(150^2,0,5),150)+mu+t(mu)

Y=as.matrix(Matrix::forceSymmetric(Y))

res=MuChPoint(Y)

plot(res,Y,L=5,shiny=FALSE)

plot(res,Y,L=1:10,shiny=FALSE,ask=FALSE)
