how to do Polar plot?
Thank you for the help in advance. I wanted to plot the data usin' polar plot as the exmple shows https://matplotlib.org/examples/api/radar_chart.html the vectors are attached as: theta=TSP rho=DNA trajectories= the direction of the wind

Creating a polar plot in MATLAB is straightforward and can be done using the polarplot function. Here's a simple example to get you started:
% Define the angle and radius
theta = linspace(0, 2*pi, 100); % Angle from 0 to 2*pi
rho = abs(sin(2*theta)); % Radius values
% Create the polar plot
polarplot(theta, rho);

You can customize the polar plot by adding markers, changing colors, and more. Here’s an example with some customizations:
% Define the angle and radius
theta = linspace(0, 2*pi, 100);
rho = abs(sin(2*theta));
% Create the polar plot with customizations
polarplot(theta, rho, '-or', 'LineWidth', 2, 'MarkerSize', 5);

You can also plot multiple datasets on the same polar plot:
You can also plot multiple datasets on the same polar plot:
% Define the angle and radius for two datasets
theta = linspace(0, 2*pi, 100);
rho1 = abs(sin(2*theta));
rho2 = abs(cos(2*theta));
% Create the polar plot
polarplot(theta, rho1, '-or', 'LineWidth', 2); % First dataset
hold on;
polarplot(theta, rho2, '-ob', 'LineWidth', 2); % Second dataset
hold off;
