hello!
i want to know how to use 'line commander'
Error: Value is not a numeric scalar value ( i wonder about this. x_p(1) = 3 x_p(2)= 2.9968 ... isn't it scalar value?)
u=line(x,y,'Color','k','LineWidth','2');
what is the matter?
in advance, person that answers my questiion. thank you!
for i=1:length(time) %length(time) =100
n2=fix(length(time)/n1); % n1=30
hold on
axis equal
x=[0 x_p(i)]; %x_p(i) is 100*1 matrix
y=[0 y_p(i)]; %y_p(i) is 100*1 matrix
u=line(x,y,'Color','k','LineWidth','2');
F(i)=getframe;
if(i==length(time))
break;
end
if(0==rem(i,n2))
else
delete(u)
end

If you are going to draw a line and then erase it, then it is more efficient to instead create the line just once and to update its XData and YData properties the other times.
