Pendulum simulation using MATLAB Second Order ODE

Objective: MAIN CODE clear all close all clc %defining the constants b = 0.05; g = 9.81; m = 1; l = 1; x0 = 0; y0 = 0 ; ct=1; %defining initial position theta_0=[0;3]; %defining time of observation t_span = linspace(0,20,500); %defining the equation [t,results]= ode45(@(t,theta)ode_func(t,theta,b,g,l,m),t_span,theta_0); %simulation…
