Thanks Michal.
Your fix for \DeclareMathOperator worked very well.
Not able to use \Aboxed inside align is not a big problem.
I changed my program not to generate it.
\boxed works OK in \begin{equation} or \[...\] so
I can used \boxed there even with mathjax.
So I think I will switch to using Matjax with make4ht for
now as it is much much faster.
Btw, I found another one. \allowbreak is not supported in
mathjax:
-------------------
\documentclass[11pt]{article}
\usepackage{amsmath,mathtools,amssymb}
\begin{document}
\begin{align*}
\left( \frac{1}{1-\left(\allowbreak 3.\,574\,4\right) ^{2}}\right)
\end{align*}
\end{document}
--------------------
But fixed it by adding
allowbreak: "{}",
To the .cfg macros you had there.
\allowbreak is autogenerated by Scientific word Latex export, and
and there is no way to disable this.
I also noticed if I use "pic-align" options, then alot of
the math do not show up on the page. So I removed "pic-align"!
The command I use now is
make4ht -ulm default -e ~/new.mk4 -c ~/nma_mathjax.cfg
filename.tex "htm,3,notoc*,p-width,charset=utf-8" " -cunihtf -utf8"
Thanks again for all your expert help. I will write a small
document to show the layout and how to use mathjax with make4ht
and add it to my tex4ht cheat sheet soon.
