I am trying to plot a phase portrait, and I want for clarity add arrows to these plots. What I want is not "quiver". I want something like the arrows in the image.
I have used, quite simply, a "plot" command solutions of ode45 to obtain the phase portrait.
Thank you in advance

The only built-in functions for drawing arrows are quiver(), quiver3(), and annotation(). annotation('arrow') is only for straight lines.
Your options would seem to be to either draw the arrow-heads yourself (perhaps using patch()), or else use annotation('arrow') with from a point to itself so that the shaft is non-existent.

I would be glad to know, if there are any developments in matlab functions in this context?

No, there are no curved arrow functions from Mathworks.
You might want to look at the File Exchange for https://blogs.mathworks.com/pick/2012/08/03/3d-arrows/ arrow3() or arrow()
