I have been reading online about solving DAE problems. It appears that BDF (Backward differentiation formula) implicit methods are able to be able to handle the incorporation of algebraic equations in…

It might be nice to have (Julia) implementations of the classical collocation schemes. Up to now, only some Radau and Gauss methods are available (as far as I know; some in `ODEInterface` and others `…

I use STRUMPACK to solve the matrix system resulting from a spectral collocation method. and I got this error feedback.
Could you please give me some suggestions.

Searching for `getMaxControl` and `getMinControl` shows that these are only used in SO and CMC. This is very confusing in any other case since it seems like setting these properties are ignored withou…

Kranc currently supports DG operators, but not efficiently. I am planning to add a feature that makes this efficient. The basic plan is to loop over a grid function in two layers: an outermost layer t…

### Goal
The continuation of periodic orbits, either from Hopf bifurcation or from orbit guess, is possible and works well. As such, computing the stability of the periodic orbit would be immensely u…
