drawing a square on the complex plane in matlab

To draw a square on the complex plane in MATLAB, we can first define the corner points of the square using complex numbers, and then plot them using the plot() function. Here's some sample code:

main.m
% Define the corner points of the square using complex numbers
z1 = -1 + 1i;
z2 = 1 + 1i;
z3 = 1 - 1i;
z4 = -1 - 1i;

% Create a vector of the corner points in a specific order
z = [z1, z2, z3, z4, z1];

% Create a plot of the square on the complex plane
figure;
plot(z, 'b.-');  % Use blue color and line style '.-' for the plot
xlim([-2, 2]);   % Set x-axis limits to show the square
ylim([-2, 2]);   % Set y-axis limits to show the square
xlabel('Real part');   % Set x-axis label
ylabel('Imaginary part');  % Set y-axis label
title('Square on the Complex Plane');  % Set plot title

In this code, we first define the corner points of the square using complex numbers z1, z2, z3, and z4. Then, we put these corner points in a vector z in a specific order, so that they form a closed shape when plotted. Finally, we use the plot() function to plot z on the complex plane, and set some formatting options for the plot (color, line style, axis limits, axis labels, and title). The resulting plot should show a square centered at the origin of the complex plane.
