Provide overoading point for arrays with custom axes

2

This PR adds a function that can be overloaded for arrays with custom axes, so that these axes are preserved in the `ParticleSwarm`optimization algorithm. The particular use case I have...

Docs for preconditioning confusing

2

I can't seem to figure out how to use preconditioning This line in the docs in particular is confusing me ```julia method=ConjugateGradient(P = precond(100), precondprep! = precond(100)) ``` First, I...

I have runt into what I believe is a bug in `ReverseDiff` I have made a gist with a program that should generate a weird behavior, along with the output...

## description I have a document that includes both plots and latex math. If I use GR as the backend by calling `gr()` in the beginning of the document, all...

Specifying optlevel for faster package loading

3

It was recently noted in a Zulip chat that JuliaFormatter takes quite a while to load, while subsequent applications of formatting are very snappy. Perhaps specifying a module specific optlevel...

IntervalArithmetic v0.20.6, Julia v1.8-rc1 ```julia julia> import IntervalArithmetic julia> rad2deg(IntervalArithmetic.Interval(1, 2)) ERROR: StackOverflowError: Stacktrace: [1] rad2deg(z::IntervalArithmetic.Interval{Float64}) (repeats 79984 times) @ Base.Math ./math.jl:334 ```

Solution for algebraic variables in DAE with callbacks

6

The following example defines a DAE on mass-matrix form with callbacks. The last state `p` is the only algebraic state and the equation `p-w(t)` forces this state to be equal...

The following code makes use of the integrator interface to take a single step of length `dt` from a state set using `set_u!`. If the procedure is repeated twice, the...

I would find it useful to have type restrictions reflected in the method signatures shown in the documentation. When I read ```julia attach!(mechanism, predecessor, successor, joint; joint_pose, successor_pose) ``` I'm...

This PR is mostly a FYI regarding https://github.com/JuliaArrays/StaticArrays.jl/issues/913 Depending on whether or not that issue is closed, you may want to switch to explicitly calling `generic_norm2` on static vectors to...
