Consider the well-known chaotic model O Henon & Helles (motivated by the motion of stars in a galaxy). The model is dp_1/dt = q1-2q1q2. P1(0) = 0.24 dp2/dt = -q2-q^2 1 + q^2 _2 p2(0) = 0.24 dq1/dt = p1. Q1(0) = 0.24. dq2/dt = p2. Q2(0) = 0.24. Integrate numerically this initial value problem using Matlab's ode113 solver with relative tolerance equal to 100 times 2ps and absolute tolerance equal to 10^-14. Integrate on the time interval [0, 100]. Plot on the same graph the evolution in time of p1, p2, q1 and q2, respectively. Integrate on the time interval [0.2 times 10^4]. Create the Poincare map of the system by taking q1(t) = 0 and plotting q2(t) against p2(t). Only plot q2(t) against p2(t) = 0 and q1(t) is interpolated output (lines)
