L=15;% length of time
ommega=10;% period
lambda = 388;
rho = 0.009;
beta=3.61e-8;
delta=0.18;
p=50000;
c=23;
f = @(t,x) [lambda-rho*x(1)-beta*x(1)*x(3); beta*x(1)*x(3) - delta*x(2); p*x(2) - c*x(3)];
tspan = [0,1];
options = odeset('RelTol',1e-1,'AbsTol',[1e-4 1e-4 1e-4]);
[t,xa] = ode45(f,tspan,[43100 0 0.0033],options);
plot(t,xa(:,1),'-'); figure
plot(t,xa(:,2),'-.');figure
plot(t,xa(:,3),'.');
