Is there away to show basic fitting on a plot whenever the code is run? rather then going to tools > basic fitting and manually doing it everytime?? I want to show the function and coeffecients on a plot everytime the code is run and the plots are produced

xy = [3.25 0.801369;
3.375 0.883622];
x = xy(:, 1);
y = xy(:, 2);
f1 = @(x) 0.6580*x-1.337209;
f2 = @(x) 0.0632*exp(0.7817*x);
f3 = @(x) 0.0379*x.^2.5890;
f1str = char(f1);
f2str = char(f2);
f3str = char(f3);
plot(x, y, 'b');
hold on
fplot(f1, x([1 end])', 'g');
fplot(f2, x([1 end])', 'k');
fplot(f3, x([1 end])', 'r');
legend({'Data', f1str(5:end), f2str(5:end), f3str(5:end)}, 'Location', 'Best')
