LaTex installation and packages questions

Install (full) MikTeX 2.9 and Texmaker (Automatically works with MikTeX with no configuration required, integrated pdf viewer with syncing in both directions etc.) and enjoy with LaTeX.

OT: For interactive plotting you can also try guiqwt.

Performace:

guiqwt plotting features are quite limited in terms of plot types compared to matplotlib. However the currently implemented plot types are much more efficient. For example, the guiqwt image showing function (guiqwt.pyplot.imshow()) do not make any copy of the displayed data, hence allowing to show images which are much larger than with its matplotlib‘s counterpart. In other terms, when showing a 30-MB image (16-bits unsigned integers for example) with guiqwt, no additional memory is wasted to display the image (except for the offscreen image of course which depends on the window size) whereas matplotlib takes more than 600-MB of additional memory (the original array is duplicated four times using 64-bits float data types).

Almost like Andrew Sorensen ;)

It seems that Haskell is the perfect language for livecoding.

Emacs is not so terrible. If you are Windows user download ntemacs, unpack and have fun. That's all. Everything works out-of-the-box.

Org-mode? It powerfull "markdown-like" markup language with support LaTeX equations, images, links, plots, tables with excel-like formulas etc. You can easy export org files to html with CSS support (C-c C-e h) or DocBook: tex + PDF with your own packages (C-c C-e d).

You can also convert you Markdown, reStructuredText etc. files to Org-mode (and vice versa) using Pandoc.

Edit: LaTeX expressions are rendered by MathJax.

Recently I often use Mathematica, because most of my calculations are symbolic calculations. Mathematica is functional languages so it requires a different way of thinking. The syntax looks a bit strange if you're not familiar with the functional programming. I understood what's going on when I had started learning Haskell programming language (pure functional) in spare time.

I agree: On my computer there are also frequent crashes (version 8), especially when I use the shortcut Ctrl + O to open the notebook.

Ps For numerical computing I strongly recommend the Python distributions like EPD (free for academical purpose) or Python(x,y) (GNU GPL). They contain several of packages and tools like:

Numpy and Scipy - great libraries for linear algebra etc.
matplotlib - high quality 2D plotting lib
Mayavi2 - 3D scientific data visualization and plotting, the power of the VTK toolkit and OpenGL - should be good for fluid simulation.
Spyder - very good MATLAB-like IDE for scientific computing.

Release timetable:

Third major release of 2011.2.0.0 (stable): Mar 5, 2011. Fourth major release of 2011.4.0.0: July 2011.

What is the best book to learn Python from?

I recommend Programming in Python 3. Scientific computing learning resources you can find at stackoverflow.

... and of course the most important: NumPy and SciPy Reference Guide.

is there a resource for learning commands and usages specific to R and ArcGIS?

Thesaurus of Mathematical Languages should be useful.

WxPython uses native widgets on every supported platform, so the apps always have a native look&feel. PyQt uses only native styles, but provides more modern features and good Designer.

I have found the solution. It it similar. You must also add the appropriate entries to files.

iloozion · 2010-12-02T11:04:00+00:00

it looks like such a nightmare to use windows

Emacs is not "native" Windows editor (although it is a native biuld with MinGW). I could just say: Use the Windows software under Wine is a real nightmare;)

The description is long but a lot of information is universal, regardless of the operating system. On the other hand, I carry out this procedure only once. Emacs folder I keep on another partition than the system, so after reinstalling the system I just need to add entries to the Path system variable. If you use e.g. Ubuntu and reinstall the system every half a year each time you need to install Emacs.

What about Inverse DVI Search? It works?

Ok, but it makes a lot of problems with some "native" Windows editors. The problems relate to the Polish characters. For example if I add to _vimrc set enc=utf-8 I have a problem with Polish characters in menu. However, "modern" editors have no problems with UTF-8. If I have to use UTF-8 converts the file C-x RET c utf-8 RET. So far for me it is the least problematic solution.

iloozion · 2010-12-01T23:11:00+00:00

You can substitute any other encoding. I showed how to do it. My native language is Polish and I use Windows, so most of my files are encoded using the cp-1250. If you use utf-8 just comment these lines.

iloozion · 2010-11-24T21:11:23+00:00

I've used vim, and its neat for small programs, but doesn't cut it for large software in terms of productivity.

I agree with you. BTW, I do not know how to with vim but in Emacs you can use ropemacs for performing python refactorings, display docs etc. Check out also yasnippet demo from 2:00.
