##Assume the following array having data in the matrix form.
@a=(
qw(1 2 3),
qw(1 2 3),
qw(1 2 3)
);
for (my $j=0;$j <= ($#{$a[0]}) ;$j++)
{
my $sum=0;
print "=======\n";
for(my $i=0;$i<=$#a;$i++)
{
print "$i$j=$a$i$j \n";
$sum+=$a$i$j;
}
push @a, $sum;
print "\n$sum\n";
}
print "\naaaa===\n@a\n";

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).

or How to display code and escape characters
are good places to start.
