Plot path of a aicraft by plot3

x0 = 0;
y0 = 0;
z0 = 0;
V = 100;

t_start = 0;
t_end = 100;
delta_t = 1;
t = t_start:delta_t:t_end;

for i = 1:length(t)
    chi = 1 + sin(i)^2;
    gamma = 1+ cos(i)^2;
    x_new = delta_t*(V*cos(chi)*cos(gamma)) + x0;
    y_new = delta_t*(V*sin(chi)*cos(gamma)) + y0;
    z_new = -delta_t*(V*cos(gamma)) + z0;
    
    x0 = x_new;
    y0 = y_new;
    z0 = z_new;
    
    plot3(x_new, y_new, z_new, '.');
    hold on
    zlabel('t')
end

I have lines of code. And i want to draw a path of aircraft in plot 3D but my result just show point. Help me!!!

t_start = 0;
t_end = 100;
delta_t = 1;
t = t_start:delta_t:t_end;
x = zeros(size(t));
y = zeros(size(t));
z = zeros(size(t));
x(1) = 0;
y(1) = 0;
z(1) = 0;
V = 100;

for i = 2:length(t)
    chi = 1 + sin(i)^2;
    gamma = 1+ cos(i)^2;
    x(i) = delta_t*(V*cos(chi)*cos(gamma)) + x(i-1);
    y(i) = delta_t*(V*sin(chi)*cos(gamma)) + y(i-1);
    z(i) = -delta_t*(V*cos(gamma)) + z(i-1);
end
plot3(x, y, z, '.');

How do i draw a path between point. Your result just show point

[Les Beckham]

Change the plot3 command as shown below:

t_start = 0;
t_end = 100;
delta_t = 1;
t = t_start:delta_t:t_end;
x = zeros(size(t));
y = zeros(size(t));
z = zeros(size(t));
x(1) = 0;
y(1) = 0;
z(1) = 0;
V = 100;

for i = 2:length(t)
    chi = 1 + sin(i)^2;
    gamma = 1+ cos(i)^2;
    x(i) = delta_t*(V*cos(chi)*cos(gamma)) + x(i-1);
    y(i) = delta_t*(V*sin(chi)*cos(gamma)) + y(i-1);
    z(i) = -delta_t*(V*cos(gamma)) + z(i-1);
end
plot3(x, y, z);
