Please help me to fix this code in Matlab, it can not run. Thank you so much

x = [0.5,1,1.5,2]; % Given x data values y = [2.3,3.2,3.7,3.8]; % Given y data values

f1 = (m*x.^2.)/(b+x.^2); % The givne fnction to fit the data Y = fit(x',y',f1,'start',[0,1]); % Calling the fit function to get the best fit % Printing the solutions fprintf('The values of coefficients m = %0.4f and b = %0.4f in the function y(x) = %s ',Y.m,Y.b,f1);

f2 = @(a,b,x) a*x+b; % linear equation for fit p = polyfit(x,y,1); % linear least-square polynomial fit % Printing the solutions fprintf('The values of coefficients m = %0.4f and b = %0.4f in the function y(x) = ax+b ',p(1),p(2));

X = 0.5:0.1:2; % x data to plot the plot(x,y,'*',X,Y(X),X,f2(p(1),p(2),X)) % plotting the data xlabel('x');ylabel('y'); legend('data','y(x)=mx^2/(b+x^2)','y(x)=ax+b','location','northwest');
