11 \item{idmc_model}{idmc\_model object as returned by \code{\link{Model}}}
12 \item{par}{model parameters values}
13 \item{var}{starting point}

19 Find periodic cycles by Newton method
22 Find periodic cycles by Newton method.
24 Convergence criterion is \code{eps} with max-norm.
27 If a valid cycle is found, a list with components:
28 \item{result}{one sample cycle point}
29 \item{eigvals}{modulus of jacobian eigenvalues associated with the cycle}
31 If a valid cycle isn't found, returns \code{NULL}.
