MatlabUDP

Synopsis

This class contains methods to read and write UDP packages between Matlab and any other network device. The core function 'MatlabUDP()' provides handles to communicate in a more comfortable way.

Usage

MatlabUDP can be called without parameters. The defaults can be changed trough input parameters (see list below). TestMatlabUDP is the example script to test MatlabUDP(). You have to run two instances of Matlab because the read method blocks until a message is received or the timeout is passed. To be able to send a message you have to specify an ip address. A reader instance needs at least a specific port to listen on.

Examples:

% without input parameters the defaults will be used
network_object = MatlabUDP();

% input parameters as struct with fieldnames equal to parameters
in_args.ip                  = '192.168.138.11';
in_args.port                = 4245;
in_args.timeout             = 2000;
in_args.max_message_length  = 1024;

network_object  = MatlabUDP( in_args );

% input parameters specified as single or multiple arguments.
network_object = MatlabUDP( 'ip', '192.168.138.11' );
network_object = MatlabUDP( 'ip', '192.168.138.11', 'port', 4245 );
network_object = MatlabUDP( 'ip', '192.168.138.11', 'port', 4245, 'timeout', 2000 );
network_object = MatlabUDP( 'ip', '192.168.138.11', 'port', 4245, 'timeout', 2000, 'max_message_length', 1024 );

Parameters

%   Possible function input parameters:
%   ------------------------------------
%
%   'ip':                   ip specifies the address of the host
%                           (default is '')
%
%   'port':                 port to listen for incoming UDP packets
%                           (default is 4245)
%
%   'timeout':              time in milliseconds to wait for an incoming packet
%                           (default is 2000)
%
%   'max_message_length':   maximal length of an incoming packet
%                           (default is 1024)
