Simulation of a simple pendulum using ODE45

Objective: The aim of the code is to solve a second order ordinary differential equation to simulate the motion of a simple pendulum. Main code: clear all close all clc theta0=[0;5]; l=1.75; t_span = linspace(0,2,100); [t, results] = ode45(@(t,theta) pendulum_animation(t, theta), t_span, theta0); displacement=results(:,1) x0=0; y0=0;…
