{\bf \large \fontfamily{cmss}\selectfont Description}\\
\hspace*{1.5cm}
\begin{minipage}[t]{13.5cm}
        {\ty plotifl} plot the normalized instantaneous frequency 
        laws of each signal component.\\

\hspace*{-.5cm}\begin{tabular*}{14cm}{p{1.5cm} p{8.5cm} c} Name &
Description & Default value\\ \hline {\ty t} & time instants (size {\ty
(M,1)})\\ {\ty iflaws} & {\ty (M,P)}-matrix where each column corresponds
to the instantaneous frequency law of an {\ty (M,1)}-signal. These {\ty P}
signals do not need to be present at the same time instants. The values of
{\ty iflaws} must be between -0.5 and 0.5.\\ \hline
