Hi!

Yes, there is a fast way, using PDL (Perl Data language):

http://pdl.perl.org/

Namely you can import your data into a piddle (a PDL object), slice the column and then perform "stats" over that:

use PDL;
$piddle = pdl @your_array;
$a = slice $piddle, '$column,:';
print stats $a;
[download]

Where '$column,:' specifies that you want the whole y range (:) of column $column to be dumped into $a. You can, for example iterate over all columns that you want. other more advanced uses are for sure possible, like taking all averages at the same time, but these are beyond my current knowledge.

Hope this helps

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
