MATLAB Code to plot a cylinder with Code

A cylinder is one of the most basic curved geometric shapes, with the surface formed by the points at a fixed distance from a given line segment, known as the axis of the cylinder. The shape can be thought of as a circular prism. Both the surface and the solid shape created inside can be called a cylinder. The surface area and the volume of a cylinder have been known since ancient times.

Short answer: use MATLAB’s built-in cylinder function:

[X,Y,Z] = cylinder;

surf(X,Y,Z)

Here is the code with proper Explanation

r = 1; % radius of cylinder

h = 2; % height of cylinder

circumference_pnts = 100; % number of points in the circumference

theta = linspace(0, 2*pi, circumference_pnts); % angle to compute 'x' and 'y'

x = repmat(r*cos(theta),2,1); % compute coordinates and put in appropriate form

y = repmat(r*sin(theta),2,1); % compute coordinates and put in appropriate form

z = [zeros(1,circumference_pnts);h*ones(1,circumference_pnts)]; % array of 'z' values: first row is basis of cylinder and second row is top of cylinder

surf(x,y,z)
