So I've designed the ground robot for a assignment and want to find to find the rmse of the simulation. I need 'how to' directions in the simplest way. Please someone help me ..

Hi @Paarth

Perhaps you are talking about the mobile robot's travelled path and the planned path.

This probably works provided that you have the Image Processing Toolbox.

x  = linspace(-5, 5, 1001);
y1 = (tanh(x) + 1)/2;
y2 = (erf(sqrt(pi/4)*x) + 1)/2;
plot(x, [y1; y2]'), grid on, xlabel('x'), ylabel('y')
legend('tanh', 'erf')
xticks([-5 -2.5 0 2.5 5])

rmse = sqrt(immse(y1, y2))

rmse = 0.0083
