Hi @stefan-k!

Can I ask you to take a look into this? Unfortunately, I can't even run a CI job here:(

[stefan-k]

Hi @npatsakula , thank you for your contribution! :) For new contributors, the CI has to be started explicitly by me.
I'm afraid a proper review will have to wait until after the holidays du to other obligations :/ Apologies!

[stefan-k]

Hi @npatsakula , this looks good to me, any idea why the CI is failing? I suspect that you'll also have to update ndarray in crates/finitediff/Cargo.toml.

Hello! I've touched up this PR in npatsakula#1
argmin-math was breaking since we were not aliasing the new "ndarray_0_16" to "ndarray". This fixes the nolinalg version, but ndarray-linalg still hasn't released a version thats compatible with 0.16 (rust-ndarray/ndarray-linalg#391) , so in order to fix that we need to wait for an upstream release.
The argmin-math tests complete successfully on my machine now, but argmin itself relies on the linalg version so thats still breaking

[stefan-k]

Thanks! Hopefully a new version of ndarray-linalg will be release soon and then we can merge this :)

Now that ndarray-linalg has released a new version, I've moved argmin's upgrading forward over in npatsakula#2
