function retstr = firstTest(instruct, outfile)%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.%  %   Author(s): M.
