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.

That's the data you had..may be you can skip few data and plot. Also have a look on quiver. YOu can specify the magnitude length etc.
