Hello, I have a set of points : x= [10,5 17,5 24,5 31,5] and Y =[5,11804923375421 3,92022009244337 2,14345898571206 1,24047882220866]
The x vector represent the doppler spread values and the Y vector represents the coherence time values, I want to demonstrate that they have an inversely relationship which means Y= a /x . I want to find the value of a and then draw the line

x= [10.5 17.5 24.5 31.5];
Y =[5.11804923375421 3.92022009244337 2.14345898571206 1.24047882220866];
f = fit(x(:),Y(:),fittype('a*x+b'),'StartPoint',[1,1]);
plot(x,Y,'or',xx,f(xx),'-b'),grid on
