how can I plot the graph of nonlinear system of ODE

% system parameters

L = 15 %treatment duration length in hour

Omega = 50 % period

alpha1 = 0.1;

alpha2 = 0.45;

kappa1 = 0.65;

kappa2 = 1;

beta1 = 0.11;

beta2 = 0.15;

epsilon = 0.05;

gamma = 0.35;

% harvesting model of votka-volttra type system of equations

dx(1)=alpha1*x(1)-alpha1*x(1)^2./kappa1-beta1*x(1)*x(2)-epsilon*gamma*x(1);

dx(2)= alpha2*x(2)-alpha2*x(2)^2./kappa2-beta2*x(1)*x(2)-gamma*x(2);

tspan = [0 1000]; % time interval

x0 = [0.5, 0.8]; % initial condition

L and omega are not in the above system of nonlinear ODE. how can I write matlab code using ode45 including L and Omega?

Can you please use edit your question that we could follow your code? I don't understand what you try to achieve and it would be useful to have the working code.
