hi
to everyone I would like to ask you how do I remove these three quiver3 objects from my patch
surf=gca;
xlim(surf,[-30 +30]);
xlabel('x');
zlim(surf,[-30 +30]);
zlabel('z');
ylim(surf,[-30 +30]);
ylabel('y');
%regola in una modalità fissa la lunghezza dela singola unita degli assi
daspect([1 1 1]);
S.Vertices=[];
S.Faces=[];
p=patch(S);
frame0=eye(4);
hold('on');
frame0V=ReferenceSystem(frame0);
function [q1,q2,q3]=ReferenceSystem(frame)
q1 =quiver3(frame(1,4),frame(2,4),frame(3,4),frame(1,1),frame(2,1),frame(3,1), 'Color', 'r');
q1.LineWidth=3;
q1.AutoScaleFactor=8;
q2 = quiver3(frame(1,4),frame(2,4),frame(3,4),frame(1,2),frame(2,2), frame(3,2), 'Color', 'g');
q2.LineWidth=3;
q2.AutoScaleFactor=8;
q3 = quiver3(frame(1,4),frame(2,4),frame(3,4),frame(1,3),frame(2,3), frame(3,3), 'Color', 'b');
q3.LineWidth=3;
q3.AutoScaleFactor=10;

Call the function with 3 output arguments to get the handle of the quiver objects.
[frame0Vq1,frame0Vq2,frame0Vq3]=ReferenceSystem(frame0);
and then delete it like this
delete([frame0Vq1,frame0Vq2,frame0Vq3])
