I have the equation of hyperbola from the fitted data. I wants to plot that hyperbola with cone to visualise actual emission processes.
Y = 7.46/(x+5.10) -0.86 is the hyperbola fit equation.
Is it possible to plot 3D image of this hyperbola inside a cone?
Your help is appreciated.

Here is an example
[T,R] = meshgrid(linspace(0,2*pi,20),0:5);
[X,Y] = pol2cart(T,R);
Z = R;
% Y = 7.46/(x+5.10) -0.86 is the hyperbola fit equation.
Z1 = 7./(R+5);
surf(X,Y,Z)
surface(X,Y,Z1)

Can I extract properties of fitted cone?How?
How to turn this into two cones, like sand clock?
Maybe better be to create sandclock from two parts
[T,Z] = meshgrid(linspace(0,2*pi,20),-3:.1:3);
R = abs(Z);
mid = R < 1;
R(mid) = (1+R(mid))/2;
[X,Y] = pol2cart(T,R);
surf(X,Y,Z)
Experiment to get the result you want

Does this cone have hyperbola too?
if we would be facing this side of the come, how would I know where the hyperbola is or which part is coverd by the given hyperbola?
Sorry I am super confused. Thank you so much.

Can you explain your question? Here is the change i made
Please draw simple sketch or something

This is the conic model I am observing, So we can see through one of the cone facing towards earth and there is a quantity that follows hyperbolic nature which is coming from inside the cone. So i am trying to plot a cone which has a hyperbola inside it to see what part of the 'see through' is covered by that hyperbola.
Thank you.
I don't get what you want
[T,Z] = meshgrid(linspace(0,2*pi,20),-3:.1:3);
R = abs(Z);
mid = R < 1;
R(mid) = sqrt(2-Z(mid).^2);
[X,Y] = pol2cart(T,R);
surf(X,Y,Z)

Oh No!
i just need a conic section with the hyperbola.
Let me tell you the other way.
A 3D plot like this,
where the equation of the hyperbola is,
and coefficients are, a = 7.45, b= -5.10, c = -0.86.
is it possible?
Thank you :)
Doesn't look like cone crossection
x = -5:.2:5;
y = 7.46./(x+5.10) -0.86;
plot(x,y)

How can we fit a hyperbola in a given data?
That is not in the list of given fit equations in cftool.
also Could this be rectangular hyperbola?
