Where is the ATen C++ API Documentation

C++

Where can I find the documentation for ATen operations that are in its API ?
For example, the C++ version of torch.linalg.solve.

What version of PyTorch does the following documentation correspond to ?
https://docs.pytorch.org/cppdocs/

On that page, under the heading ATen, the following text appears:
‘This Tensor class and all other symbols in ATen are found in the
at:: namespace, documented here.’

If I select the link here, I get the following web page which does not exist:
https://pytorch.org/cppdocs/api/namespace_at.html#namespace-at

If you go to the web page:
https://docs.pytorch.org/cppdocs/api/

The page title is C++ API Reference. When I try to search for ‘solve’ on
that page, I get links to resolve, but not solve.

The following script builds doxygen for the ATen routines. This just contains prototypes but together with the pytorch python documentation, one can use the C++ ATen routines.
