Hi all?
I have set up a system of differential equations to solve an age structured model for disease transmission. I have it running okay in MATLAB. However, I want to move to my models from MATLAB to Octave.
On running the model in Octave, it generates the following errors:
> [time,Mv,M,S,I,R,Ir]=solve_rate1([0 30],3,beta,options);
Number of arguments supplied correct.
***** Integration in progress. Please wait... *****

Is there a missing package that I may be required to install. I have used the ODE solver: ode45.
Waiting to hear from you.
