Documentation of certain functions is hidden

[sairajat]

The documentation of tensor.h is missing a lot of contract functions in the tensor class.
Attached is the screenshot of how the current documentation looks like. It is missing the functions contract, contract2, double_contract, and scalar_product. They are still defined in the tensor.h header file but not documented there.
Is that intentional?

None of these are member functions. Do they show up on a different part of the page?

[sairajat]

No, they do not appear anywhere on the page.

They donot even show up in the documentation search. Invert is also amongst one of those. The documentation is built incorrectly atleast for the Tensor.h file.

I wished I could say what causes this, but doxygen is a bit of a black box to me. One would have to come up with a smaller test case (say only this one file) and play with different ideas of coercing doxygen to include everything as intended.
