how to create contant conical strucure in matlab mainwriting ?

I want to create a contant conical structure in matlab mainwriting. after inserting values, it is not plotting structure. Can anyone please guide here?

I'm not really sure what you mean by "constant conical structure". Are you just trying to draw a simple cone? If so, what are the inputs? What is the code you're trying to use?

Thank you so much DGM for asking. Kautak answers me very precise. Thank you so much both of you for concern and answer.

Hi Alia,

It is my understanding that you are seeking guidance on how to create a constant conical structure in MATLAB using its plotting functions.

A cone can be described parametrically as follows:

Radius (r) varies linearly from the apex to the base.

Height (z) is a linear function of radius.

The angle (θ) around the cone varies from 0 to 2π.

Here is an example of how to create a conical structure in MATLAB:

% Define cone parameters 
height = 5; % Height of the cone 
baseRadius = 2; % Radius of the base of the cone 
numPoints = 50; % Number of points in the mesh 

% Create mesh for the angle (theta) and height (z) 
[theta, z] = meshgrid(linspace(0, 2*pi, numPoints), linspace(0, height, numPoints)); 

% Calculate the radius at each height 
r = (baseRadius / height) * z; 

% Convert cylindrical coordinates (r, theta, z) to Cartesian coordinates (x, y, z) 
x = r .* cos(theta); 
y = r .* sin(theta); 

% Plot the cone 
surf(x, y, z) 
colormap('default') % Set the color map 
shading interp % Interpolate colors across lines and faces 
axis equal % Equal aspect ratio for all axes 
xlabel('X') 
ylabel('Y') 
zlabel('Z') 
title('Conical Structure') 

This code creates a conical structure by defining a mesh grid for the angle (θ) and height (z), then calculating the radius (r) at each height based on the linear relationship between the radius and height.

The generated structure would look like:

Remember to adjust the height, baseRadius, and numPoints variables as needed for your specific purpose.

I hope this explanation helps you create and visualize a conical structure in MATLAB with ease.
