Hi
I would need in a document several equations which are aligned as in
http://tex.stackexchange.com/a/167908/6941
How can I use the following latex formula in orgmode?
--8<---------------cut here---------------start------------->8---
\begin{proof} The proof is a follows:
\begin{align}
(x+y)^3&=(x+y)(x+y)^2\\
&=(x+y)(x^2+2xy+y^2)\\
&=x^3+3x^2y+3xy^3+x^3.\qedhere
\end{align}
\end{proof}
--8<---------------cut here---------------end--------------->8---
I have effectrively
--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \usepackage{amsmath}
* The equations
\begin{equation}
\begin{align}
(x+y)^3&=(x+y)(x+y)^2\\
&=(x+y)(x^2+2xy+y^2)\\
&=x^3+3x^2y+3xy^3+x^3.\qedhere
\end{align}
\end{equation}
--8<---------------cut here---------------end--------------->8---
but with latex fragment preview (C-c C-x C-l) I only get an empty frame.
How can use this align environment in org?
I could use
--8<---------------cut here---------------start------------->8---
\begin{eqnarray*}
\hat{f}(x) & \propto & \sum_{\nu} \frac{|F(\nu)H(\nu)|^2}{|N(\nu)|^2}
\frac{G(\nu)}{H(\nu)} e^{\frac{2 \pi i \nu x}{N}}\\
& \propto & \sum_{\nu} \frac{|F(\nu)|^2}{|N(\nu)|^2} H(\nu) H^*(\nu)
\frac{G(\nu)}{H(\nu)} e^{\frac{2 \pi i \nu x}{N}}\\
& \propto & \sum_{\nu} H^*(\nu) G(\nu) e^{\frac{2 \pi i \nu x}{N}}
\end{eqnarray*}
--8<---------------cut here---------------end--------------->8---
but eqnarray is apparently bad (see link above).
Thanks,
Rainer

This seems to a problem with your setup of preview latex. It
should work just fine.
For me the following org file works as expected -- also with
previewing the equation.
--8<---------------cut here---------------start------------->8---
#+LaTeX_header: \usepackage{amsmath} %% needed explicitely for org-preview-latex
* Test align
\begin{align}
(x+y)^3&=(x+y)(x+y)^2\\
&=(x+y)(x^2+2xy+y^2)\\
&=x^3+3x^2y+3xy^3+x^3.\qedhere
\end{align}
--8<---------------cut here---------------end--------------->8---
I do not seem to have any special setup for previewing latex,
though...
Sorry to be of no further help.
Regards,
Andreas

But it doesn't:
- I started emacs with -Q
- executed the following in scratch to load newest org
--8<---------------cut here---------------start------------->8---
;; Load up Org Mode and Org Babel for elisp embedded in Org Mode files
(add-to-list 'load-path "~/.emacs.d/org-mode/lisp")
(add-to-list 'load-path "~/.emacs.d/org-mode/contrib/lisp")
;; load up Org-mode and Org-babel
(require 'org)
--8<---------------cut here---------------end--------------->8---
- pasted this in an org buffer
--8<---------------cut here---------------start------------->8---
#+LaTeX_header: \usepackage{amsmath} %% needed explicitely for org-preview-latex
* General conditions
The general conditions for all parametrizations are the following:
\begin{equation}
x=\sqrt{b}
\end{equation}
\begin{equation}
\begin{align*}
(x+y)^3&=(x+y)(x+y)^2\\
&=(x+y)(x^2+2xy+y^2)\\
&=x^3+3x^2y+3xy^3+x^3.\qedhere
\end{align*}
\end{equation}
\begin{eqnarray*}
\hat{f}(x) & \propto & \sum_{\nu} \frac{|F(\nu)H(\nu)|^2}{|N(\nu)|^2}
\frac{G(\nu)}{H(\nu)} e^{\frac{2 \pi i \nu x}{N}}\\
& \propto & \sum_{\nu} \frac{|F(\nu)|^2}{|N(\nu)|^2} H(\nu) H^*(\nu)
\frac{G(\nu)}{H(\nu)} e^{\frac{2 \pi i \nu x}{N}}\\
& \propto & \sum_{\nu} H^*(\nu) G(\nu) e^{\frac{2 \pi i \nu x}{N}}
\end{eqnarray*}
--8<---------------cut here---------------end--------------->8---
- did C-c C-x C-l (which runs (org-preview-latex-fragment)) on each
formula and I got the attached screenshot [1]

Nested align in equation is incorrect format.
-k.

Where is proof defined? You may need to add specific packages to
org-latex-packages-alist.
In any case, I find that it is safer generally to enclose all LaTeX
fragments in a LaTeX block: #+begin_latex ... #+end_latex.

The proof and the ".\qedhere"

Good idea - but then the preview does not work anymore?
Sorry for the noise and thanks,

I tried that "\begin{align}...\end{align}" code with "C-c C-x C-l", it
generate a very back quality image like this:

What settings do you have for image creation in org? What is
org-latex-create-formula-image-program?
For instance, I have the following settings:
#+begin_src emacs-lisp :results none
(setq org-format-latex-options '(:foreground "white" :background "black" :scale 3 :html-foreground "Black" :html-background "Transparent" :html-scale 1.0 :matchers ("begin" "$1" "$" "$$" "\\(" "\\["))
org-latex-create-formula-image-program 'imagemagick
)
#+end_src
and I get something along these lines:

You'll probably not want to change the foreground and background colours
if you have a light background emacs theme.
The quality of the image may also be a function of your LaTeX default
packages and fonts.

Thanks Eric, that solved the preview issue. But when export it to ODT
file, the image is still as bad as the one I post before. (Export to PDF
is fine).

One step forward at least... with respect to ODT export, I'm not best
placed to answer this. Maybe somebody else can chime in? My equations
come out fine when I export to ODT but I don't have anything customised
that I can see. Maybe check the org-odt- variables?

I haven't followed the thread, but ox-odt should export to mathml by
default. I use this to produce mathml:
(setq org-latex-to-mathml-convert-command
"latexmlmath \"%i\" --presentationmathml=%o")

Hi Rasmus,
thanks for the above.
I don't believe the default is to export to mathml. At least, for me,
this doesn't happen. But, to be brutally honest, I'm more than a little
confused about what is possible or not in ODT export. I don't use it
often, mostly because almost all of my documents have some maths in
LaTeX form, but there are indeed cases where it would be nice to have
the capability of exporting maths to ODT.
Setting the variable mentioned above doesn't work for me either. I had
to install the latexml package (on Ubuntu) to have the command available
but I don't know where to get the jar file that may be needed
(cf. org-latex-to-mathml-jar-file). Any help in this regard would be
welcome. Searching the mailing list doesn't bring up anything useful.
Thanks,
eric

For me, when I eval the following from emacs -q I get odt.
(require 'ox-odt)
(setq org-latex-to-mathml-convert-command
"latexmlmath \"%i\" --presentationmathml=%o")
E.g. export: \(x\).

It’s getting better. I exported a large document recently, and Nicolas
fixed a lot of bugs.

None. At least two methods are supported: latexmlmath and some .jar file,
perhaps mathtoweb.jar or something like that?

Run from emacs -q and check your *messages*. You should see something
like this in the buffer:
Formatting LaTeX using mathml
Creating MathML snippet 1...
Wrote /tmp/ltxmathml-in5102GLn
Running latexmlmath "\(x\)" --presentationmathml=ltxmathml-out5102TVt

I am using org from git, fairly recent version.
There must be some other configuration setting, maybe something outside
org that enables latexml to work?
thanks,
eric

This is triggered if (org-format-latex-mathml-available-p) returns nil.
Go through each step of this function (in org.el). My guess is that
latexmlmath is not in your PATH, at least according to Emacs...

Got it! org-latex-to-mathml-convert-command is one of those variables
that has to be either set globally (which I don't want) or I have to use
#+bind:. Setting it locally is no good!
Works very well now!
Thanks for all the help,
eric

align is defined in amsmath. amsmath is loaded by default by org. I use
amsmath extensively and there's no problem. I don't escape my math
environments and IMO you shouldn't as they would then be ignored by ox-odt
and ox-html.
As Eric point out you'd typically use amsthm for proofs. You need to add
this to your document. The proof env. is predefined in amsthm, though.
Hope it helps,
Rasmus

Make sure to C-c C-c on the keyword.
