Functions to plot the coefficients, the gain and the phase functions.
Usage

)Arguments
- x
coefficients, gain or phase.
- nxlab
number of xlab.
- add
boolean indicating if the new plot is added to the previous one.
- ...
other arguments to
matplot.- zero_as_na
boolean indicating if the trailing zero of the coefficients should be plotted (
FALSE) or removed (TRUE).- q
q.
- legend
boolean indicating if the legend is printed.
- legend.pos
position of the legend.
- xlim
vector containing x limits.
- n
number of points used to plot the functions.
- normalized
boolean indicatif if the phase function is normalized by the frequency.
