Solving a second order ODE using lsode and the simulation of a damped pendulum motion

Objective: %% Program to solve an ODE IVP of damped pendulum motion clear all close all clc %specifying the time range t = linspace (0,20,50); theta_0 = [0 3]; %solving the ODE theta = lsode(\'odefun_pendulum\',theta_0,t); %plotting the solution subplot(2,2,3) plot(t,theta(:,1),\'color\',\'g\',\'linewidth\',4)…
