Mean square root error from different files

For example, I have files called A.txt and B.txt.
A.txt
Code:
#x yj
1 1
2 4
3 9
4 16
5 25
6 36
7 49
8 64
9 81
10 100

B.txt
Code:
#x ^yj
1 1 
2 8
3 27
4 64
5 125
6 216
7 343
8 512
9 729
10 1000

I would like to count the mean square root error, which has the formula exactly the same with the picture. Image

So far, I have this code to combine them:
Code:
#! /usr/bin/perl -w

use strict;

open FP1,"A.txt";
open FP2,"B.txt";
my ($l1,$l2);
while(1)
{
  $l1=<FP1>; chomp $l1;
  $l2=<FP2>; chomp $l2; 
  last unless(defined $l1 or defined $l2);
  print "$l1 $l2\n";
}
close FP2;
close FP1;

After it combine it will become this text file:
Code:
1 1 1 1
2 4 2 8
3 9 3 27
4 16 4 64
5 25 5 125
6 36 6 216
7 49 7 343
8 64 8 512
9 81 9 729
10 100 10 1000

The column#2 = yj and column#4 = ^yj. Any idea?

gtkdoc-mktmpl(1)					      General Commands Manual						  gtkdoc-mktmpl(1)

NAME
gtkdoc-mktmpl -- GTK DocBook documentation generator. SYNOPSIS
gtkdoc-mktmpl [ See below ] DESCRIPTION
gtkdoc-mktmpl This creates or updates the template files which contain the manually-edited documentation. (A template is a simple text form which is filled in with the description of a function, macro, enum, or struct. For functions and macros it also contains fields for describing the parameters.) This script reads in the existing templates, found in tmpl/*.sgml, moves these files to tmpl/*.sgml.bak, and then recreates the .sgml files according to the structure given in the file MODULE-sections.txt. Any new templates added, or new function parameters, are marked with FIXME so you can do a grep to see which parts need updating. Any templates which are no longer used (i.e. they are remove from MODULE-sections.txt) are placed in the file tmpl/MODULE-unused.txt. If they are included again later they are automatically copied back into position. If you are certain that these templates will never be used again you can delete them from MODULE-unused.txt. Any parameters to functions which are no longer used are separated from the rest of the parameters with the line <!-- # Unused Parameters # -->. It may be that the parameter name has just been changed, in which case you can copy the description to the parameter with the new name. You can delete the unused parameter descriptions when no longer needed. EXAMPLE
See /usr/share/doc/gtk-doc-tools/examples, for a makefile.am and a configure.in example file. AUTHOR
