I am unable to getting the arrows in the plot by using the quiver. Plot shows all the calculated data tip values but not showing the arrows.

Code as given below. Please help me for this problem.

[X,Y]=meshgrid(-2.5:0.1:2.5,-2.5:0.1:2.5);

Ur=(1+((Y-X)/2.5)-((X*Y)/(2.5^2)));

for i=1:size(X,1)

for j=1:size(X,2)

Uz1(i,j)=(3-(3.75/X(i,j)));

end

figure(1)

q=quiver(X,Y,Ur,Uz1,'ShowArrowHead','on','LineWidth',1,'MarkerSize',3);

q.Color = 'red';

q.AutoScaleFactor='1';

[X,Y]=meshgrid(linspace(-2.5,2.5,10));

Ur=1+((Y-X)/2.5)-((X.*Y)/2.5^2);

for i=1:size(X,1)

for j=1:size(X,1)

Uz1(i,j)=(3-(3.75/X(i,j)));

end

figure(1)

q=quiver(X,Y,Ur,Uz1,'LineWidth',1);

q.Color = 'red';

If you use autoscale factor along with arrowhead on it will distort the quiver diagram and misintrepret the plot.
