export latex align to html?

export latex align to html?

[Neal Becker]

I have an align environment:

#+begin_latex
\begin{align*}
\Lambda= & \max_{k,l}\left|
\sum_{i=0}^{M-1}r_{i+l}x_{i}^{*}e^{j2\pi\Delta_{f}ki}+\sum_{i=M}^{2M-1}r_{i+l}x_{i}^{*}e^{j2\pi\Delta_{f}ki}+\cdots\right|
\\
\approx & \max_{k,l}\left|
\sum_{m}e^{j2\pi\Delta_{f}kmM}\sum_{i=mM}^{(m+1)M-1}r_{i+l}x_{i}^{*}\right|
\end{align*}
#+end_latex

That exports fine to latex, but not html.  Is there a way to do this?

Sure - I get perfect output by just leaving out the
#+begin_latex/#+end_latex markers. Underneath, mathjax is being used,
but I don't think I have done any customization: it should work right
out of the box.

The attached works for me.  

You can have conditional code on the latex src block to generate raw
latex when exporting to latex and an image when exporting to
html.  Check out

* Intro
I have an align environment:

#+begin_src latex :file alignedequation.png :results raw
\begin{align*}
\Lambda= & \max_{k,l}\left|
\sum_{i=0}^{M-1}r_{i+l}x_{i}^{*}e^{j2\pi\Delta_{f}ki}+\sum_{i=M}^{2M-1}r_{i+l}x_{i}^{*}e^{j2\pi\Delta_{f}ki}+\cdots\right|
\\
\approx & \max_{k,l}\left|
\sum_{m}e^{j2\pi\Delta_{f}kmM}\sum_{i=mM}^{(m+1)M-1}r_{i+l}x_{i}^{*}\right|
\end{align*}
#+end_src

That exports fine to latex, but not html.  Is there a way to do this?
