# \xymatrix - Where can I get it?

Forums:

Hi I'm a semi Latex literate (Texerate?) PhD student who's trying to draw some commutative diagrams (aren't we all?) Anyway, I've had a look at some of the PM entries with diagrams and they use the command "\xymatrix". My poor little version of Tex (MacTex, on the Mac believe it or not) doesn't seem to recognise these. Do I need a particular package? In which case which one? Any other bright ideas? Or do I just follow the time honoured solution of calling Bill Gates rude names (It's probably not his fault, it won't make it work, but it makes me feel better)?

Great! Yep my package did have it. Now all I have to do is work out how to use it! I googled and am downloading a manual as we speak (or to be precise, as I type)

Thanks ever so much

Stevie

### Re: \xymatrix - Where can I get it?

It turns out that simple things are pretty easy to do. There are a number of entries on PM that may help you understand how to use the package. For example, look at the entry on the 5 lemma, or the 9 lemma.

If you need further examples, just ask and I can send you some.

Just a quick note to say thanks for the help. Yep, it is nicely designed and easy to use isn't it!
Cheers

Don't know much about these things, but it seems to me that it should. Look on google for "TUGBoat" (Tug = Tex User Group) to find freebie downloads and advice.

### Re: Disc space

That would be a considerable fraction of disc space-right?For my limited use of Latex how do I get Latex help without my having to download such a huge sw pl?

### Re: Disc space

Hi Devaraj,
Use LaTeX on PM (do not save changes! just use only the Preview) and when you want, make a copy on MS Word and store it on you HD. If you need traslate it to another place, use a pendrive. So you may look your LaTex work by copy-paste on LaTex PM page whenever you want.

### Re: Disc space

Miktex has also a Basic version, which needs about 200MB of space. It should be enough unless you need some special packages. And best of all, when you need such packages, miktex will automatically download and install them. I've been using it for almost two years and needed to install additional packages only twice.

### Re: Disc space

I have downloaded & installed miktex (basic).What are the packages I have to instal or does the include all the basic pkgs pl?

### Re: Disc space

This should already be enough for a basic usage.
The installer changes the system variable PATH, so on the commandline, you can type "latex filename.tex" and your .tex file will be translated to a .dvi file and then "dvips filename.dvi" for a .ps file (or "pdflatex filename.tex" which creates a .pdf file).

First convert it to PDF with the following command:

pdflatex example.tex

Then click "add to Papers" in the left sidebar of PlanetMath and enter your data there.

Add URL of the PDF file at "URLs for any remote content (one per line)".

Be warned that PlanetMath is buggy regarding submission of papers: e.g. one of my papers become not owned by me and I now cannot delete or change it.

If your paper got mistakenly owned by someone else you can request to edit it and rectify the matter-right?

Secondly if you publish a paper in PM no journal would be willing to consider it for publishing-right?

### Re: \xymatrix - Where can I get it?

The package is xypic, which you can google. But it should be part of any reasonable TeX distribution.

### Disc space

I have Compaq 3.5 and Windows xp.If I want to download Latex sw will it occupy too much of hd space?
