🚀 The feature, motivation and pitch

I'm using log1p and logcumsumexp for complex number in my case. However, as of Pytorch 1.13.0, this has not been supported.
I found a discussion here and an old PR here, but it seems like the PR has been abandoned.
I would like to resurrect this and working on it if there's no one is working to implement it already.

Alternatives

The alternative is to implement it in python, but it would be nice to have it supported in Pytorch.
