Hello,
I came across this issue (recreated here using example code):
```
julia> using ODE
julia> function f(t, y)
# Extract the components of the y vector
(x, v) = y

at the moment, due to how we define functions and the fact that our models need to support ForwardDiff.jl, we have the ability, in theory, to generate fully symbolic versions of an EoS. for a proof of…

When intra-layer reaction rate in CHR2 is too high, the initialization or the solver fails due to the small time scales.
In particular the characteristics time for reaction is 100 times less than th…

Is there a way to specify a tolerance on the cost rather than ftol/gtol/xtol?
When using least_square to find multivariate, bounded roots (please suggest alternatives if it exists in scipy.optimiz…

We have a quick implementation of ADI:

This could live in this package.

Hi,
Would it be possible to ask the user the functions a,b,c and for a robin BC and it will provide an `equation` to solve:
`∇(a(x,u)∇u) + ∇(b(x,u)u) + c(x,u) u = 0`
