draw a plane in matlab

To draw a plane in MATLAB, we can create a meshgrid to define the x, y, and z coordinates of the plane, and then plot it using the surf function.

Here's an example code:

main.m
% Define the x and y limits of the plot
x_min = -5;
x_max = 5;
y_min = -5;
y_max = 5;

% Create a meshgrid for the x and y coordinates of the plane
[X, Y] = meshgrid(x_min:0.2:x_max, y_min:0.2:y_max);

% Define the equation of the plane (in this case, a simple xy-plane)
Z = 0*X + 0*Y;

% Plot the plane using the surf function
surf(X, Y, Z)

% Set the axes labels and title
xlabel('X')
ylabel('Y')
zlabel('Z')
title('The XY Plane');

This code will create a plot of the XY-plane with x and y values ranging from -5 to 5, and a step size of 0.2.

You can modify the equation of the plane by changing the values in the Z variable. For example, Z = 2*X + 3*Y would produce a plane tilted in the x-y direction with a slope of 2 in the x-direction and 3 in the y-direction.
