Hello Everybody I have 4 vectors x,z,dx,dz which respectively are coordinate of x,coordinate of z, displacement in x direction ,displacement in z direction. I want to plot a vector field graph for displacement, to see the amount and direction of displacement on each point.size of each vector is (110000,1).

What I could think of was

[X,Z]=meshgrid(x(:,1),z(:,1));

D=sqrt(dx.^2+dz.^2);

quiver(X,Z,D,dx)

But didn’t work at all. Any help would be highly appreciated as I am still new to matlab. Thank you in advance

#x,z are evenly spaced, I mean with different intervals.

Thank you @KSSV

I did as you said,but its too dense and can not see anything(i attached the file).also when i zoom in to the graph all the arrows have the same direction! the slip(or dislocation) suppose to change the direction after some time.
