plot euler angles for each time in matlab

main.m
        ```
        % input euler angles (in radians) and time
        % phi, theta, psi, and t should have the same size
        phi = [0.1, 0.2, 0.3];
        theta = [0.4, 0.5, 0.6];
        psi = [0.7, 0.8, 0.9];
        t = [1, 2, 3];

        % plot euler angles against time
        figure;
        plot(t, phi, 'r', t, theta, 'g', t, psi, 'b', 'LineWidth', 2);
        legend('\phi', '\theta', '\psi');
        xlabel('Time (s)');
        ylabel('Euler angles (rad)');
        title('Euler angles over time');
        grid on;
        ```

        This code will plot the euler angles `phi`, `theta`, `psi` against time `t` on a single graph with different colors for each angle. The `legend` function adds a legend to the plot and the `grid on` command adds a grid to the plot for better visualization. 

        Note that if you have euler angles in degrees, you need to convert them to radians before plotting.
