Thanks for the ping, @geetaakshata! Can you have the text "Frobenius inner product" link to https://en.wikipedia.org/wiki/Frobenius_inner_product? I'm not sure what syntax would be used to create the external link. You might need to look at source code for other NumPy web documentation to figure that out.

Ah, the age-old question: how do you make a hyperlink in sphinx? Only the sages know 😜

Kidding but not really, it's the most common sphinx issue people run into. Relevant StackOverflow answer, which links to the ReStructuredText docs: https://stackoverflow.com/questions/17189038/generating-an-external-link-in-sphinx

Also numpy's linter enforces a 79 character line limit, see the test results.
