No Arrows showing in plot When using quiver

I am new to Matlab. Trying to use quiver to plot a velocity field. This is my code that gets to the plot but doesn't show any arrows.

[x,y] = meshgrid(0:0.2:5,0:0.2:5);

u = 2./x;

v = 2.*y./(x.^2);

figure

quiver(x,y,u,v)

As the grid starts from 0 and you have used this zero in the reciprocal to get (u,v) you will get inf in the u,v.; quiver uses maximum value of u and v to scale the arrows and plot. Try to repalce inf with some other value or avoid zero.

[x,y] = meshgrid(1:0.2:5,1:0.2:5);
u = 2./x;
v = 2.*y./(x.^2);

figure
quiver(x,y,u,v,1,'r')

Worked perfectly. Learned something about the scaling too. Thank you!
