Great!
I think many Stata users aren't even aware of what Mata is. I only
start using it by accident when I wanted to calculate the pooled
sample covariance matrix for a data set of males and females. Since
then I can barely program without this easy to use and powerful tool.

Yes, but not as soon as you would like.  Writing it has been on my to-do list
and I'm still working on it.

In the meantime, I highly recommend the "Mata Matters" column in the
Stata Journal.  There have been four so far:

      Translating Fortran
             SJ 5(3), 3rd quarter 2005, 421-441

      Using views onto date
             SJ 5(4), 4th quarter 2005, 567-573

      Creating new variables (Sounds boring, isn't)
             SJ 6(1), 1st quarter 2006, 112-123

      Interactive use
             SJ 6(3), 3rd quarter 2006, 387-396

That's 49 pages of recommended reading.

The most recent column could use a better title.  Mata is, obviously, a
programming language.  The most recent column, however, is about using Mata
interactively to avoid writing programs and ado-files.
