Codul matlab folosit este:

N=50000; a=4;
vp=zeros(N,1); vp(1)=0;
e=zeros(N,1); e(1)=1; de=0.0001;
m=zeros(N,1); m(1)=a*e(1);
for i=2:N
e(i)=e(i-1)+de;
m(i)=a*e(i-1);
dvp=(2/m(i-1))*de*(1-a*vp(i-1));
vp(i)=vp(i-1)+dvp;
end
h = figure;
set(h, ‘WindowStyle’, ‘Docked’);
subplot(2,1,1);
plot(e,sqrt(vp),’r-‘); hold on;
xlabel(‘Energie’);
ylabel(‘Viteza’);
subplot(2,1,2);
plot(sqrt(vp),m,’b-‘); hold on;
xlabel(‘Viteza’);
ylabel(‘Masa inertiala’);
