I am currently working on a proceedings paper, and have realised after finishing it that only specific packages are permitted - one of which is not amsmath
. As a result, many of the nice equations that I have written can now no longer be built. To save me switching back to \begin{cases} \end{cases}
and giving up, I thought I would try asking on here to see if anyone could provide me with a solution?
I cannot define add any new commands before \begin{document}
, so everything must be done after that point. I thought about trying to grab the relevant components from the style file, but to be perfectly honest I am not a TeX-wizard and have no idea whether this would even work.Could anyone provide me with a work-around, so that I can still use align and aligned, but by doing so after \begin{document}
?
If it helps, the packages I am permitted to use are:
\usepackage{mathptmx}
\usepackage{helvet}
\usepackage{courier}
\usepackage{type1cm}
\usepackage{graphicx}
\usepackage[bottom]{footmisc}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{amsbsy}
\usepackage{amscd}
\usepackage{amstext}
\usepackage{dsfont}
\usepackage[english]{babel}
\usepackage{color}
\usepackage{graphics}
\usepackage{epsfig}
\usepackage{subfigure}
\usepackage{wrapfig}
\usepackage{psfrag}
\usepackage{color}
\usepackage{url}
\usepackage{verbatim}
\usepackage{algorithm}
\usepackage{algorithmic}
Edit: An MWE is as follows:
\documentclass{svmult}
\usepackage{mathptmx}
\usepackage{helvet}
\usepackage{courier}
\usepackage{type1cm}
\usepackage{graphicx}
\usepackage[bottom]{footmisc}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{amsbsy}
\usepackage{amscd}
\usepackage{amstext}
\usepackage{dsfont}
\usepackage[english]{babel}
\usepackage{color}
\usepackage{graphics}
\usepackage{epsfig}
\usepackage{subfigure}
\usepackage{wrapfig}
\usepackage{psfrag}
\usepackage{color}
\usepackage{url}
\usepackage{verbatim}
\usepackage{algorithm}
\usepackage{algorithmic}
\begin{document}
\begin{equation}
\label{InitSystemNL}

-like styles are possible, but could depend on your application. Most notably would be using a regulararray
environment. However, it's difficult to address this fully without seeing some form of minimal working example (MWE).amsmath
? That to me seems kind of ridiculous. I don't quite understand why there should be such restrictions. I know if I had gotten this far and something and was rejected for a package reason I would just copy the entire package and make it part of my content!! :-) I know that this is not a very helpful comment, but Welcome to TeX.SE.align
-like structures into something likearray
?
