Store the diagonal of Diagonal

I was wondering whether or not it would be a good idea to special-case the type `Diagonal` to only store the internal vector representing the diagonal of the matrix? I'm...

missing values OK for simulation but not inference

I am just starting out with some experiments using Soss, and came up with the following simple model of a review process with articles and reviewers. The model is happy...

Out of bounds error from

I get a cryptic out-of-bounds error trying to run inference on the following model. It samples from the prior just fine, the error originates from DynamicHMC. The stack trace is...

Add an example of tangent-space regularization

Add an example of tangent-space regularization for identification of smooth dynamical systems. Proposed in [Machine Learning and System Identification for Estimation in Physical Systems, 2018](https://lup.lub.lu.se/search/publication/ffb8dc85-ce12-4f75-8f2b-0881e492f6c0)

Method ambiguity for `*`

```julia julia> using Symbolics julia> @variables u[1:2, 1:5] 1-element Vector{Symbolics.Arr{Num, 2}}: u[1:2,1:5] julia> Q2 = I(2) 2×2 Diagonal{Bool, Vector{Bool}}: 1 ⋅ ⋅ 1 julia> dot(u, Q2, u) ERROR: MethodError: *(::Diagonal{Bool,...

Basic operations on `Num` have `Any` return type

Would it make sense to try to make basic operations between `Num`, such as the one below, type stable, at least in their return type? ```julia julia> @code_warntype a/a MethodInstance...

Some missing methods

While translating the example https://github.com/JuliaRobotics/RigidBodyDynamics.jl/blob/master/examples/6.%20Symbolics%20using%20SymPy/6.%20Symbolics%20using%20SymPy.jl from using SymPy to using Symbolics.jl, I encountered the following missing functions ```julia Base.typemax Base.typemin Base.eps ``` Which I naively defined as ```julia Base.eps(::Type{Num}) =...
