MATLAB Web Server

Additional Application Examples

The easiest way to learn how to create MATLAB applications that send and receive data over the Web is to analyze the sample programs included with your MATLAB Web Server distribution. To access these sample programs, open the file <matlab>/toolbox/webserver/wsdemos/index.html in your browser. By analyzing the code used to create these examples, you can expand upon them to create more complex MATLAB Web Server applications.

Data Display

The players demonstration function illustrates a basic use of the MATLAB Web Server to display data over the Web. The file players.txt contains a data base with information about The MathWorks softball team.

PLAYER	POSITION	AVERAGE	AT BATS
Ron Berg	First Base	.337	30
John Theytaz	Second Base	.294	22
Charles Carmody	Third Base	.261	34
Debby Oldman	Shortstop	.287	29
Jack Pirrotta	Right Field	.256	27
Josh Tillson	Center Field	.301	31
Eugene Goldbrick	Left Field	.281	31
Donna Navillus	Pitcher	.222	32
Anna Alman	Catcher	.290	30

players uses a few MATLAB commands to read the tab-delimited file, convert the data to an HTML file, and display the output in a Web browser. No input form is needed for this application, only a URL. The URL can be entered directly in your browser or as a live link in another page.

The URL for the players example is

• http://<your_domain>/cgi-bin/matweb.exe?mlmfile=players& 
  

on Windows NT. (On Solaris/Linux use matweb instead of matweb.exe.)

The output looks like

If you would like to experiment on your own with a similar simple application, use players as a model to create an M-file that reads your own text file, e.g., myfile.txt, and places data into a MATLAB structure. To display the result in your Web browser, use the above URL, changing the value of the mlmfile argument to the name of your new M-file. Also, copy the entry for players in matweb.conf and change the name of the application within the brackets [] to the one you have chosen.
