%PLOTP Plot trajectory
%
% Convenience function to plot points stored columnwise.
%
% PLOTP(P) plots a set of points P, which by Toolbox convention are stored
% one per column.  P can be 2xN or 3xN.  By default a linestyle of 'bx'
% is used.
%
% PLOTP(P, LS) as above but the line style arguments LS are passed to plot.
%
% See also PLOT, PLOT2.
