Modeling samples with xCos

[16.63 kB]

	Here are presented several simple problems on mathematical modeling in ecology.
I think that it can be useful for beginners in Xcos. 
1)Simple ecological model: dx/dt=kx.
2) Verhilst ecological model: dx/dt=ax-bx^2
3) The Volterra-Lotka ecological model: dx/dt=ax+bx^2+cxy, dy/dt=ky+mxy.
Where, x and y population number, t - time; a, b and k constant coefficients of
an ecosystems.
