We've had several requests in the past for constant species, and my general advice was if one wanted `A` to be constant don't write `A --> B` but write `A --> A + B` or `0 --> B` with rate `k*A`. The …

Hello all,
I am wondering how to solve linear and nonlinear equations containing array/matrix variables using NLsolve. For example, if
a=[1 2 3; 4 5 6; 7 8 9]; b=[1; 2; 3];

I'm looking to use `extract_eq()` to help with the `nlmixr2` package. It typically uses nonlinear, mixed-effect models that are defined by multiple equations.
For that, I was l…
