%FUNCTION_TEMPLATE Guide for creating MATLAB Web Server applications.
%   <FUNCTION_TEMPLATE>(INSTRUCT) where you replace the
%   "<FUNCTION_TEMPLATE>" with the name of the MATLAB Web 
%   Server application you wish to create.
%   <FUNCTION_TEMPLATE>(INSTRUCT, OUTFILE) is the same as
%   the single argument version but also includes an optional
%   argument, OUTFILE, for writing HTML output to a file (for
%   stand-alone testing).
%
%   Modify this file to create your own application.  Be sure
%   to save the modifications as <FUNCTION_TEMPLATE>.m where
%   <FUNCTION_TEMPLATE> is replaced with the name of your 
%   application M-file.
%
%   INSTRUCT is a structure created by the matweb program.
%   It contains fields corresponding to the HTML form fields
%   in the HTML form that you have created from the file
%   INPUT_TEMPLATE.HTML.  In that HTML file  there
%   should a hidden field, called "mlmfile" that references
%   the M-file that you create here.

% STEP 1
% Initialize the return string.
retstr = char('');

% STEP 2
% Set working directory. The variables INSTRUCT.MLDIR 
% and INSTRUCT.MLID are provided automatically to all
% MATLAB Web Server applications that use the matweb program.
% Use the directory in MLDIR for writing graphics files 
% in a location that the HTTPD can read.
cd(instruct.mldir);

% STEP 3
% Get the HTML form input variables (from the HTML form that
% you created from INPUT_TEMPLATE.HTML) and use them in your
% program.  See the sample M-files in the wsdemos directory
% for examples.
P.Length = str2double(instruct.Length);
P.Width = str2double(instruct.Width);
P.Frequency = str2double(instruct.Frequency);
P.Diameter = str2double(instruct.Diameter);
P.Thickness = str2double(instruct.Thickness);
P.conductivity = str2double(instruct.conductivity);
P.hole_space = str2double(instruct.hole_space);


% STEP 4
% Perform your MATLAB computations, graphics file creations,
% etc. here:
%SEe=20*log10(P.Space^2*sqrt(P.Length*P.Width)/(P.Diameter^3))+41.8*P.Thickness/P.Diameter+2.68;
%SEm=20*log10(P.Space^2*sqrt(P.Length*P.Width)/(P.Diameter^3))+32*P.Thickness/P.Diameter+3.83;

A=32*P.Thickness/P.Diameter;
N=5.79e-5*P.Frequency*P.Thickness;
R=20*log10((1+N)^2/(4*N));
if 
SEe=

% STEP 5
% Put variables that you want to put into your HTML output document
% in an output structure.  You create an HTML output document from
% OUTPUT_TEMPLATE.HTML.  See the sample M-files in the wsdemos
% directory for examples.
outstruct.SEe = SEe;
outstruct.SEm = SEm;

% STEP 6
% Call the function HTMLREP with the output structure you just
% created and the file name you created from OUTPUT_TEMPLATE.HTML.
% Replace <OUTPUT_TEMPLATE.HTML> with the name of the HTML output
% file you created using OUTPUT_TEMPLATE.HTML.
% This call fills the string RETSTR to return and optionally 
% writes the output as a file if a valid filename is given as the
% second argument to the present function. 
templatefile = which('shield2.html');
if (nargin == 1)
   retstr = htmlrep(outstruct, templatefile);
elseif (nargin == 2)
   retstr = htmlrep(outstruct, templatefile, outfile);
