I have tried mightily to get LyX to break long equations. I’ve studied multiple
pages at stackexchange, both LaTeX and LyX, and can’t seem to get anything to
work.
I have had luck in the past with the second large block of code at this page:
https://stackoverflow.com/questions/2904807/lyx-breaking-long-formula-lines
but today I have some problems with it.
First, it doesn’t work if the \text command appears inside my own LaTeX code that appears
between \begin{dmath} and \end{dmath} or if I try to use the trick twice in the same
document. (That’s a tentative analysis of the problem.) Specifically, LyX runs at 100%
CPU eventually gives me a chance to abort and then follows up with this additional
message: "The external program pdflatex finished with an error. It is recommended
you fix the cause of the external program's error (check the logs)."
Plus, I now want to to apply the line breaking to a line within an aligned
environment (Insert -> Math -> Aligned Environment in the menu system.) This is
causing things to look even worse, even though I added two “aligned” lines to the
referenced code block. (If you look at the code you’ll see the obvious places to add
the lines.)
How do LyX-ers handle this? Is there “LyX” solution to breaking long equations?
I’m OK with some ad hoc solution for now, or some ERT if it works.
Thanks,
Jerry
I've never used the breqn package, but with ordinary and AMS math
environments, hitting Ctrl-Enter in the middle of a long formula will
break it (inserting a line break, \\, in the LaTeX output). If that
doesn't achieve what you want, perhaps you could post a minimal example
and a specification of what the output should look like.
