The following code seems to solve my problem.

Code:
#!/usr/bin/perl -w

use constant DIM => 4;

sub Shift_elements_right{
    my ($ref) = shift;
    for($j = 1 ; $j <= DIM ; $j++){
	for ($i = 1 ; $i <= DIM ; $i++ ){
	    $ref->[$j + 1][$i + 1] = $ref->[$j][$i];
	}
    $ref->[$j + 1][1] = $ref->[$j][DIM];
    }
}


# Initialize
for ($i = 1; $i <= DIM; $i++){
	$weights[1][$i] = $i;
}

# Shift call
Shift_elements_right(\@weights);

# Print output.
for ($i = 1; $i <= DIM; $i++){
    for ($j = 1; $j <= DIM; $j++){
	print "Weight $i : $weights[$i][$j]\t";
    }
    print "\n";
}

git-symbolic-ref

GIT-SYMBOLIC-REF(1)						    Git Manual						       GIT-SYMBOLIC-REF(1)

NAME

       git-symbolic-ref - Read, modify and delete symbolic refs

SYNOPSIS

       git symbolic-ref [-m <reason>] <name> <ref>
       git symbolic-ref [-q] [--short] <name>
       git symbolic-ref --delete [-q] <name>

DESCRIPTION

       Given one argument, reads which branch head the given symbolic ref refers to and outputs its path, relative to the .git/ directory.
       Typically you would give HEAD as the <name> argument to see which branch your working tree is on.

       Given two arguments, creates or updates a symbolic ref <name> to point at the given branch <ref>.

       Given --delete and an additional argument, deletes the given symbolic ref.

       A symbolic ref is a regular file that stores a string that begins with ref: refs/. For example, your .git/HEAD is a regular file whose
       contents is ref: refs/heads/master.

OPTIONS

       -d, --delete
	   Delete the symbolic ref <name>.

       -q, --quiet
	   Do not issue an error message if the <name> is not a symbolic ref but a detached HEAD; instead exit with non-zero status silently.

       --short
	   When showing the value of <name> as a symbolic ref, try to shorten the value, e.g. from refs/heads/master to master.

       -m
	   Update the reflog for <name> with <reason>. This is valid only when creating or updating a symbolic ref.

NOTES

       In the past, .git/HEAD was a symbolic link pointing at refs/heads/master. When we wanted to switch to another branch, we did ln -sf
       refs/heads/newbranch .git/HEAD, and when we wanted to find out which branch we are on, we did readlink .git/HEAD. But symbolic links are
       not entirely portable, so they are now deprecated and symbolic refs (as described above) are used by default.

       git symbolic-ref will exit with status 0 if the contents of the symbolic ref were printed correctly, with status 1 if the requested name is
       not a symbolic ref, or 128 if another error occurs.
