I need to draw a curve for illustration purposes in a figure together with some other more specific values. I'm looking for something like this:
I need it to be smooth like that one, and have the ability to adjust it. How could i do that?

If you have a few waypoints, you might just be able to do something like this:
x = [0 1 2 2.5 3 4 5 6 6.2 7 8];
y = [0 0.5 1 0.95 0.65 0.25 0.8 1.3 1.3 0.7 0.1];
xf = linspace(0,8,100);
yf = interp1(x,y,xf,'spline');
plot(xf,yf)
axis equal
There are also ROI drawing tools (drawfreehand, imfreehand), but I don't know how you'd easily go about making such an object into an open curve. Depending on how it needed to be integrated into the figure content, I'd probably just export the figure and add the curve in an image editor that can do practical bezier curves interactively.

figure;
x = linspace(0, 2*pi, 1000);
y = sin(x).^2 + sin(x / 2).^2 .* x / 10;
plot(x, y)
