Hi,

  I was trying to define a pretty printing environment for matlab 
files. The basic requirements that I have are

% Numbers should be highlighted in a different color
% Identify floating point numbers 1.1 and 1e-3.

% Identify brackets
% ()[]{}

% Identify Punctuation
% ,;<=> ...

% Identify Operators
% ^ + - / * .^  .*

% Idenfity strings (enclosed in ' ' and " ")

% Identify lines starting with % as comments. Show them
% a different color. Identify %{ ... %} blocks as comments

% identifiers
function return case if else elseif do for while end

% variables
gt,lt,gt,lt,amp,abs,acos,acosh,acot,acoth,acsc,acsch,
[snip].... a huge list

The syntax is similar to both perl and MP. I had a look at the 
verb-*.tex files and tried to write verb-matlab. My attempt is 
attached.

However, it does not work correctly. There are somethings that I could 
not figure out.

1. How to change the comment identifier. Matlab uses % as line 
comments and %{ .... %} as block comments.
2. For some reason Matlab variables are not recognized.
3. The punctuations are not identified.
4. '...' is not recognized as a string. The ' is output as a right 
quotation mark and not _neutral_ '.

What would be a good way to include tex commands in the comments?

Matlab recognizes %% as a special comment (begining of a cell). Is it 
possible to somehow translate %% into \MATLABcell, which is \bf by 
default but the behaviour can be changed if desired?

See attachment verb-matlab.tex for my attempt and test.tex for an 
example.

Thanks
Aditya
