From what I can see the standalone.html is a static html page that displays an input box and a button thus

<HTML>
<BODY>
<FORM ACTION="/cgi-bin/mycgimagic.exe">
<P>Please specify the size:
<INPUT NAME="size" SIZE="5"><BR>
<INPUT TYPE="SUBMIT" VALUE="Go!">
</FORM>
</BODY>
</HTML>

[download]

When you press the button on the page, the request sent to the webserver is to execute the program /cgi-bin/mycgimagic.exe which is the compiled version of mycgimagic.m.

Using the size parameter extracted from the environment variable QUERY_STRING, the program computes the magic square and the response received by your browser is an html page created using the fprint(1,text) statements withing the program starting with this one

fprintf(1,'Content-type: text/html\n');

and later these 

function createTable(M)
s = size(M);
fprintf(1,'<table border = "2">');
for i=1:s(1)
    fprintf(1,' <tr>');
    for j=1:s(2)
        fprintf(1,['  <td>',num2str(M(i,j),'%4.2f'),'</td>']);
    end
    fprintf(1,' </tr>');
end
