cholesky takes as argument a square symmetric
positive definite matrix M of size n.
cholesky returns a symbolic or numeric matrix P. P is a
lower triangular matrix such that:

Warning If the matrix argument A is not a symmetric matrix,
cholesky does not return an error, instead cholesky will
use the symmetric matrix B of the the quadratic form q
corresponding to the (non symmetric) bilinear form of the matrix A.
