Math & Science ⇒ alignat environment with no top/bottom margins

[CaptainProton]

I would like to have my alignat environment to have no top and bottom margins. I found the following solution for the standard align environment which does exactly what I want:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
8
9
\makeatletter
\newenvironment{myalign*}{%
  \setlength{\mathindent}{0pt}%
  \setlength{\abovedisplayskip}{-\baselineskip}%
  \setlength{\abovedisplayshortskip}{\abovedisplayskip}%
  \start@align\@ne\st@rredtrue\m@ne
}%
{\endalign}
\makeatother

Can someone help me to adjust it for the alignat environment? I can't figure it out myself.

Thank you very much, it works! I would have never figured this out myself.
