Research direction

Start by reviewing the existing dot, t(), map, and conj() APIs and how complex data types are handled. The scope still needs deciding between complex conjugation, inner products, or both; done would mean the selected operations work for complex data and remain valid or redundant for strictly real data.

Written by the indexing model from the issue text.

Description

I was wondering whether there is any interest in implementing complex conjugation and/or inner products for complex data types?

For example, implementing a a.ct() which would be equivalent to a.t().map(|v| v.conj()) and a a.inner_product(b) which would be equivalent to a.dot(b.ct()).

This would obviously be only for complex data types though I guess that for strictly real data, these could still 'work' (and be redundant with dot and t()). I'm not sure whether that would complicate significantly the implementation or not.
