[Haskell-cafe] Automated Differentiation of Matrices (again)

[adam vogt]

Hi Florian,

The restriction Edward described is gone: here's an unboxed vector of
ForwardDouble:
<https://gist.github.com/aavogt/6bee72717148123a187c>. But I don't think
there's been any work to make hmatrix's Field class have a ForwardDouble
instance. I don't know of a ReverseDouble either.

Regards,
Adam
