error bar in curve fitted graph
显示 更早的评论
Sir,
I am having two data x and y . After that I have fitted data using curve fitting tool (using polunomial of degree 1). Then I got plot with curve fitted graph. I want to get error in this graph as error bar. How to get?

x = (-1:0.1:1)';
y = asinh(x/0.5);
f = fit(x, y, 'poly1')
err = y - f(x);
errorbar(x, y, err), hold on
plot(x, f(x), '--.'), grid on
xlabel x, ylabel y
legend('data', 'fitted poly1', 'location', 'se')
