How to get rid of this line that connects the last and first point, I have made it white so its barely visible, but is there a way to not plot it?

WayPTS = [5,4,1;
    7,5,1;
    7,7,1;
    9,6,1;
    10,8,1];
plot3 (WayPTS(:,1), WayPTS(:,2), WayPTS(:,3),'black',...
      [WayPTS(end,1) WayPTS(1,1)],[WayPTS(end,2) WayPTS(1,2)],[WayPTS(end,3) WayPTS(1,3)],'white')

plot3 (WayPTS(:,1), WayPTS(:,2), WayPTS(:,3),'black');

You could also try increasing the 'LineWidth' to 2 or more to make it appear even smoother and more solid :

plot3 (WayPTS(:,1), WayPTS(:,2), WayPTS(:,3),'black', 'LineWidth', 2);
grid on;
xlabel('x', 'FontSize', 18);
ylabel('y', 'FontSize', 18);
zlabel('z', 'FontSize', 18);
