Creating a 3D surface plot from a 2D shape

I am wanting to create a surface plot of an axisymmetric body using the matlab surfnorm command.

I have the geometry as an X row and Y column vectors.

The line shape is open at one end, and as I had been attempting to utilize the cylinder command with a spurious shape being generated.

I had attempted to use a rotational matrix to generate a set of Z points to create a full set of X,y,z points of the surf command but I feel at a dead stop how to implement this, with loop functions etc.

is there an alternative command or method i could use to create this shape in 3D?

How do you intend to add z info? One option is to create a vector of the same length as x (or y) using the ones or zeros function (your shape will still be flat but will be viewable as a 3D object). e.g.

z = zeros(size(x,1),1); % shape centred at z = 1

z = ones(size(x,1),1); % shape centred at z = 0

you can add noise too

z = zeros(size(x,1),1)+rand(size(x,1),1); % add noise

Besides this I'm not sure how you will arbitrarily add 3D info to your 2D shape

What is the axis of rotation for your 2D curve?
