Colleagues: is there an straightforward Scilab approach for solving the three coupled nonlinear differential equations of first order given by the Standard Model of Epidemics?
S= number Susceptible: S'=-aSI I= number Infected: I'=aSI - bI R= number Recovered: R'=bI whereby 'a' is the transmission coefficient, 'b' the recovery factor (after Reed-Frost 1928). Initial values for S, I, R are available. Thank you Heinz _______________________________________________ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
