From http://www.oooforum.org/forum/posting.php?mode=quote&p=2559

It seems that oomath is bombing out on a certain formula I wrote.
This also happens when I'm embedding the formula in a text document.
Thanks to some help, I now know what the problem is, but I cannot see what is wrong here.
What I did is then retype the whole formula in oomath and save it. When I open it again oomath hangs.

Here is the formula:
Code:

func lim csub{x toward infinity}{{alignc 2 - func sin x} over {alignc x^3+3}} newline
"For all " x " it holds that " newline
matrix {
alignr -1 #{}<={} #alignc func sin x #{}>={} # 1 ##
alignr 1 # {} >= {} #alignc func -sin x #{}>={}# -1 ##
alignr 3 # {} >= {} #alignc 2 - func sin x #{}<={}# 1 ##
alignr {alignc 3}over{x^3+3} # {} >={} #{alignc 2 - func sin x}over{alignc x^3 + 3}#{}<={}#{alignc 1}over{x^3+3}
}

Strange indeed. I can past your formula in a Math object, everything looks OK. then I close the doc, I reopen and Bang, gone is OOo.This is definitely an 'issue', worth exploring by the technies out there.

It is the Matrix part of your formula that is causing the problem. Anyway, for what you wanted to to you could have worked with a table or tab settings, filling in each element with a separate formula object. The formula did not crash OOo anymore when I removed all the alignclausules you used. They are not needed anyway. Good luck!

Oddly enough, that actually gives me another idea. I have to check something first but I'll keep you all posted. Might be interesting for everyone.

Well! I just never new you could use 'newline' like that to make a new line. Guess I've still got a lot to learn about the possibilities of Math. I sure do which there was a reference of all of its features ....

Strange indeed... I'm using the latest OOo version, 1.1. It didn't crash. I've saved the code with Math. I've created a text document and inserted the formula. Didn't crash either. I sincerely hope you've solved it by now...

There is a reference. Go the the help index under and you'll see a refernece... It has every command. It's all you need to use Math after you study mathematics for a while.

It's in the Wellcome to OpenOffice.org Math page (Help system), third link, called: "Reference"
