Recommended method for creating custom derivatives / gradients using Duals?

6

The documentation currently [describes](http://www.juliadiff.org/ForwardDiff.jl/stable/dev/contributing.html#Adding-New-Derivative-Definitions-1) how to add custom derivative definitions using DiffRules. However, it seems that this only covers basic custom derivatives. For example, I don't know how this approach...

Inverse transformation for empty vectors fails

1

I am working on an algorithm where I want to define a transformation for a vector of length `p`. Importantly, `p` may be zero. This transformation is part of a...

Add Julia matrix exponential?

7

I needed a pure Julia implementation of matrix exponentiation, so I updated an old 2012 gist to Julia 1.0, see [here](https://gist.github.com/sdewaele/2c176cb634280cf8a23c5970739cea0e). I am happy to contribute it to this repo...

lyap adjoint more robust to different inputs

A difference between the adjoint input type and the types to the original lyap can cause issues in computing the adjoint. They are address by converting the adjoint argument to...

No IntelliSense for packages developed using a relative path

8

IntelliSense does not work on relative paths. These are the steps to reproduce this issue: 1. Generate a package using the package manager, `]generate IntelliTest`. The package contains the standard...

Refer to binary files in package directory as artifact for relocatable apps

18

Applications and packages frequently depend on (small) binary files. For example, [XLSX.jl](https://github.com/felipenoris/XLSX.jl) uses template Excel files. Other applications may include a small dataset, a logo image, etc. These can conveniently...
