Description

This is one of the steps at #10465. Links there point to motivating discussion.

This is a simple function which mostly exists to make it obvious that there is an all-in-one function to do this.

It would appear that conjugate() method could stand some speed improvements for large matrices, though a few more experiments would be needed to be sure it was the creation of a new matrix, or the actual conjugations.

Looks good to me. Too bad we can't tab on things like A.conjugate()...
