Matrix algebra support?

[jluttine]

Does this package support matrix algebra operations? For instance, does this support HMatrix, Repa or Accelerate or some other way of getting gradients for functions involving matrices? I'm looking for a Haskell alternative for Python autograd package.

its definitely a gap that needs to be fixed :)

Hi! Has there been any progress with this? I am able to differentiate boxed vectors, but fail to do so for storable or unboxed types. Is there a way to provide reverse mode ad for these types? I am not too familiar with ad, and I think that the Reverse data type is not of fixed size (e.g., a tree), but maybe I am missing something! Thank you for your help!
