Hello everyone, I have what ought to be a simple question. I’m trying to include multiple binary indicator variables (dummy variables) within an ODE system: B1 and B2 either take the value 0 or 1, enabling two different estimates for a parameter being fit to two groups of data; e.g., (a1*B1 + a2*B2…

[image] zhrandell: real R[Tm, nLev, 2]; for (n in 1:nLev) { R[ , n, ] = integrate_ode_rk45(resourceLoss, Y0_obs[n], t0, th, theta, x_r[n], x_i); } I think something like this should be possible: real R[Tm, nLev, 2]; for (n in 1:nLev) { R[ , n, ] = integrate_ode_rk45(re…

I’m glad that it works now.
