I have 4 normalized vectors that represent the edges of error ellipse, how do I plot a cone between them that represent the error area up until a certain point(x*10,y*10,z*10) for example.
in other words, a semi cone with no head ( there is an "head" if the error in the head is tiny enought to count as the same point for every vector).
for example I have a data of vectors 2x3 where first line is the direction vector and line 2 is point of origin

right now I have a code of drawing ellipse at a given height which then I loop to give me the ellipse error over length
function ellipse(left,right,up,down,height)
left(1,1:3)=left(1,1:3)*(height/left(1,3))+left(2,1:3);
right(1,1:3)=right(1,1:3)*(height/right(1,3))+right(2,1:3);
up(1,1:3)=up(1,1:3).*(height/up(1,3))+up(2,1:3);
down(1,1:3)=down(1,1:3).*(height/down(1, 3))+down(2,1:3);
x=mean([min([left(1),right(1),up(1),down(1)]),max([left(1),right(1),up(1),down(1)])]);
y=mean([min([left(1,2),right(1,2),up(1,2),down(1,2)]),max([left(1,2),right(1,2),up(1,2),down(1,2)])]);
t=0:0.1:2*pi;
Xt=0.5*norm(left-right)*cos(t)+x;
Yt=0.5*norm(up-down)*sin(t)+y;
Z=t-t+height;
plot3(Xt,Yt,Z,'color','green');
hold on;
