hello, I am doing a GUI with an axes and several buttons, and i have to be able to draw a few kinds of arrows. By now, if have found out the function: annotation('arrow'...), The problem I have with this function is that I want the arrow to be only inside the axes, not everywhere, so I'm wondering if there is a way do it.
Furthermore I'd like to draw my own arrow, the one shown in the following picture (or similar...)

You can use the plot() or line() commands to draw whatever you want.
Did you search for "arrow" in the FileExchange already?

but to draw that do i need the "function" of the curved line and then i add the arrowhead?
I know it may be a stupid question but i'm kind of new with matlab thanks

You can define the coordinates by a function or manually. You can draw the array with a graphics program and import it as image.
Again: Did you search in the FileExchange already? You find dozens of implementations for drawing arrows there. Looking in the code will reveal different possible methods.
