{title:Description}

{p 4 4 2}
Mata is a matrix programming language that can be used by those who want to
perform matrix calculations interactively and can be used by those who
want to add new features to Stata.


{title:Remarks}

{p 4 4 2}
This manual is divided into five sections.  Each section is organized
alphabetically, but there is an introduction in front that will help you get
around.

{p 4 4 2}
If you a new to Mata, here is a helpful reading list:
Start by reading 

{col 9}{hline 61}
{col 9}{...}
{bf:{help m1_first:[M-1] first}}{...}
{col 29}{...}
Introduction and first session
{col 9}{...}
{bf:{help m1_interactive:[M-1] interactive}}{...}
{col 29}{...}
Using Mata interactively
{col 9}{...}
{bf:{help m1_how:[M-1] how}}{...}
{col 29}{...}
How Mata works
{col 9}{hline 61}

{p 4 4 2}
You may find other things in section {bf:[M-1]} that interest you.  
For a table of contents, see 

{col 9}{hline 61}

{bf:{help m1_intro:[M-1] intro}}{...}
{col 29}{...}
Introduction and advice
{col 9}{hline 61}

{p 4 4 2}
Whenever you see a term that you are unfamiliar with, see

{col 9}{hline 61}
{col 9}{...}
{bf:{help m6_glossary:[M-6] glossary}}{...}
{col 29}{...}
Mata glossary of common terms
{col 9}{hline 61}

{p 4 4 2}
Now that you know the basics, if you are interested, you can look deeper into
Mata's programming features:

{col 9}{hline 61}
{col 9}{...}
{bf:{help m2_syntax:[M-2] syntax}}{...}
{col 29}{...}
Mata language grammar and syntax
{col 9}{hline 61}

{p 4 4 2}
{bf:[M-2] syntax} is pretty dense reading, but it summarizes nearly
everything.  The other entries in [M-2] repeat what is said there but with
more explanation; see

{col 9}{hline 61}
{col 9}{...}
{bf:{help m2_intro:[M-2] intro}}{...}
{col 29}{...}
Language definition
{col 9}{hline 61}

{p 4 4 2}
Along the way, you will eventually be guided to sections [M-4] and [M-5].
[M-5] documents Mata's functions; the alphabetical order 
makes it easy to find a function if you know its name but makes learning 
what functions there are hopeless.  That is the purpose of [M-4] -- to
present the functions in logical order.  See
