To work with matrices, use
PDL.
Update
I've got it! It's super easy. Just pile the matrices one on another, and then project the 3D matrix by average in the z dimension:
#!/usr/bin/perl
use warnings;
use strict;
use PDL;
sub load {
my ($filename) = @_;
open my $FH, '<', $filename or die $!;
return pdl(map [split], <$FH>)
}
my $matrix = cat(map load($_), @ARGV);
print average($matrix->reorder(2,0,1));
Old contents
I'm not yet familiar with it, so I had to compute the average myself by adding the matrices and dividing the result by their number, but maybe there already is a function to compute the average per element, or at least to apply a function per element.
#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };
use PDL;
sub load {
my ($filename) = @_;
open my $FH, '<', $filename or die $!;
return pdl(join "\n", map { chomp; "[$_]" } <$FH>)
}
my @matrices = map load($_), @ARGV;
my $result = $matrices[0];
$result += $_ for @matrices[ 1 .. $#matrices ];
$result /= @ARGV;
say $result;
($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

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).
