Hi, could anybody help me to point out why axis equal does not work in my code?
figure(19)
quiver( P1(1), P1(2), D0(1), D0(2), 0 ,'b','LineWidth',2)
hold on
quiver( P0(1), P0(2), D00(1), D00(2), 0,'b' ,'LineWidth',2)
quiver( P1(1), P1(2), D9(1), D9(2), 0, 'g' ,'LineWidth',2)
quiver( P9(1), P9(2), D99(1), D99(2), 0, 'g' ,'LineWidth',2)
quiver( P1(1), P1(2), D10(1), D10(2), 0,'r' ,'LineWidth',2)
quiver( P10(1), P10(2), D100(1), D100(2), 0 ,'r','LineWidth',2)
quiver( P1(1), P1(2), D(1), D(2), 0,'k' ,'LineWidth',2)
plot(x9,y9,'g')
plot(x10,y10,'r')
hold off
axis equal
xlabel('Re')
ylabel('Im')
set(gca, 'FontSize', 14)

Can you attach an image then showing what the plot looks like?

@Emma: What do you expect "equal axes" to look like and what do you observe instead?

According to doc axes the command axis equal does:
Use the same length for the data units along each axis.
So it adjusts the data units or in other word the DataAspectRatio. What do you want to do instead? Maybe you mean:
axis square

Thank you for your answers, I found the solution to my problem which was to replace 'axis equal' with 'daspect([1 1 1])'.

@Lawrence: The OP did not tell us, what exactly is wanted. axis square sets the PlotboxAspectRatio to [1,1,1], while axis equal adjust the DataAspectRatio. You do not mention also, what is supposed to be done. If you add this detail, other readers might profit also.

Emma: Thans, I encounted the same problem, i.e., (axis equal) not working, and the daspect([1 1 1 ]) fixed it.
