8.65.2.1 Show equation number only once in align environment

https://tex.stackexchange.com/landing/r/digest?cta=question&id=17528

I want the equation number to be shown only at the last line, or better, somewhere in the middle of all. So instead of (1), (2), ... only (1). 
I use \begin{align} ... \end{align}

8.65.2.2 The \bar and \overline commands

https://tex.stackexchange.com/landing/r/digest?cta=question&id=22100

I want to represent, say, the closure of a set or the extended reals, e.g., $\bar{\mathbb{R}}$ but unfortunately this creates a bar that is much too small (horizontally) and can barely be seen. On the ...

This question led to a new package: 
matlab-prettifier 
Does anybody have a quick and easy way to typeset some relatively long MATLAB code in the appendix? I looked up a few methods, and the mcode ...

8.65.2.4 Command for argmin or argmax?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=5223

How can you get the argmin or argmax in Latex? Two solutions I found are: 
\underset{x}{\operatorname{argmax}} 
\DeclareMathOperator*{\argmin}{arg\,min} 
Any other ideas?

8.65.2.5 Tabular: title above and caption below?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=15282

I have a table that I would like to put the Title above and a caption below. Intuitively (though I know how troublesome intuition can be in something like LaTeX), I should be able to do as below:

8.65.2.7 How to add an empty line between paragraphs?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=135134

I have two sections which I'd like to separate by an empty line. Every time I press Enter, LyX removes that empty line between paragraphs. How do I prevent this?
