hold on
axis equal
axis off
b = 0:pi/40:pi/4;
c = 0:pi/20:pi/2;
P4vct=nan(numel(b),2);
for k = 1:numel(b)
P1=[-15,0];
P2=[-5,0];
plot([P1(1) P2(1)],[P1(2) P2(2)],'LineWidth',5,'Color','black');
A=[0,0];
h{1} = viscircles(A,5,'LineWidth',2,'Color','black');
B = A+[10*cos(b(k)-pi/4),10*sin(b(k)-pi/4)];
h{2} = viscircles(B,5,'LineWidth',2,'Color','green');
C = B+[10*cos(c(k)-pi/2),10*sin(c(k)-pi/2)];
h{3} = viscircles(C,5,'LineWidth',2,'Color','blue');
P3=C+[5*cos(c(k)-(pi/2)),5*sin(c(k)-(pi/2))];
P4=C+[15*cos(c(k)-(pi/2)),15*sin(c(k)-(pi/2))];
h{4} = plot([P3(1) P4(1)],[P3(2) P4(2)],'LineWidth',5,'Color','black');
P4vct(k,:) = P4;
h{5} = plot(P4vct(:,1),P4vct(:,2), '--','LineWidth',3,'Color','blue');
drawnow();
pause(0.5);
delete(vertcat(h{1:4}));
end

"hold" it in what sense? You want the last two frames to be displayed on top of each other at the end, but during the main part of the loop only one frame is to be displayed at a time??

At the bottom of the loop, only call delete() if it's not the last one:
if k < numel(b)
delete(vertcat(h{1:4}));
end
