Hi Everyone.
I have my vehicle model to move on the track. So, i have 3 data sets x,y ,z and by using these vectors i genrated a 3D track.I would like to smooth my path by using filters. I tried with low pass and sgolay filter but they are not working well or maybe i didn't use them correctly.Can anybody help to smooth the track.i have attached a matlab file.Thank you

Try this
a = [0 9 10 9 8 7 6 4 2 -12 4 3 5 8 7 11 14 6 5 0 -4 -3 -15 -11 -9 -4 0];
b = [0 0 5 10 2 10 7 12 6 12 14 20 18 12 17 6 3 -20 -4 -20 -2 -20 -2 9 -1 0 0];
c = [0 0 0 0 0 0 0 0 0 10 0 0 0 0 0 0 0 -15 -5 -10 0 15 2 10 -2 0 0];
t = linspace(0, 1, numel(a));
tq = linspace(0, 1, 10*numel(a));
x = pchip(t, a, tq);
y = pchip(t, b, tq);
z = pchip(t, c, tq);
plot3(a,b,c)
hold on
plot3(x,y,z)
grid on
xlabel('X(m)');
ylabel('Y(m)');
zlabel('Z(m)');
You can also try to replace pchip with spline() and makima()
