MATLAB Web Server | ![]() ![]() |
Using matlabserver
When we viewed the source of the webmagic1.html
file, we observed the line of HTML code
and we noted that this line establishes communication with MATLAB. matweb
is a program that resides on the HTTP server and communicates with matlabserver
. matweb
requires information found in matweb.conf
to locate matlabserver
(which could be running on a different machine).
matweb Program
matweb
is a client of matlabserver
that uses Common Gateway Interface (CGI) to get data from HTML forms. It transfers the information to matlabserver
, which then runs applications written in M-files to produce responses.
When the MATLAB Web Server is installed, matweb
is placed in <matlab>/webserver/bin/
arch
for all architectures. This placement allows you to run matweb
on a machine having the HTTPD
but not having MATLAB installed and being of a different architecture from the server.
For HTTP server access you must also place a copy of matweb
in the directory denoted by the /cgi-bin
alias. The installation process places a copy in <matlab>/toolbox/webserver/wsdemos
to run the sample applications.
matweb.conf
To connect with matlabserver
, matweb
requires information stored in the configuration file matweb.conf
. Create this file inside the directory denoted by /cgi-bin
, along with the matweb
program. Use the copy in<matlab>/toolbox/webserver/wsdemos
as a guide.
An instance of matweb.conf
looks like
Multiple application configurations must appear in the same file. Each variable appears on a separate line followed by an equal sign =
, which is then followed by a value, e.g., mlserver=parrot
. Applications are delineated by the main application entry point name (M-file) in square brackets []
. For example, [webpeaks]
is on one line followed by all its variables and corresponding values. Note that webmagic
does not require an mldir
entry because it does not generate any graphics or save any files. Use the %
or #
character at the beginning of any line to comment it out.
All the fields that can be contained in matweb.conf
are described in Table 3-2.
After you create a new MATLAB Web Server application and enter its configuration data into matweb.conf
, you need to restart matlabserver
before you can use the application.
matweb M-File
Looking again at the source from the webmagic1.html
file (see webmagic Input), observe that the line
sets argument mlmfile
to the value webmagic
. The mlmfile
argument contains the name of the MATLAB M-file to run.
matlabserver
uses the value of mlmfile
obtained from the matweb
M-file, matweb.m
, (webmagic
in this example) to run the MATLAB application. webmagic
takes the input data from webmagic1.html
, computes the magic square of the requested dimensions, and outputs the results using webmagic2.html
as a template.
