function is_valid = trajValidateWaypoints(waypoints, num_wp, cycle)
% trajValidateWaypoints checks that the waypoints form a valid trajectory
%   The function returns true if the given waypoints form a valid
%   trajectory, otherwise it returns false
%
% Inputs:
%   points          trajectory waypoints [x; y; z] in local geodetic
%                   coordinate system
%                   (3xN vector), in m
%
%   num_wp          the total number of waypoints
%                   (scalar), dimensionless
%
%   cycle           enable automatic repetition of the given course
%
% Outputs:
%
%   valid           hold result if the waypoints form a valid trajectory
%                   (logical), dimensionless
%
% Syntax:
%   is_valid = trajValidateWaypoints(traj, waypoints, degree, cycle)
