I have velocity ,v, and discharge, q, vectors . I want to draw hysteresis plot between the two. I used plot_dir function but it can't allow me to have the plot with good view and resolution. Is there any way of plotting it?

I used this function but failed

plot_dir(v,q)

Thanks for your help.

Any function that give that shows the beginning and end of successive points with arrow is acceptable. Thanks again.

在 MATLAB Online 中打开

x = rand(10,1);
y = rand(10,1);
quiver(x(1:end-1),y(1:end-1),diff(x),diff(y),0);

Please accept an answer if it helps you.
