MATLAB contains Java support, including the javax.sound.midi.* classes  
(although it somewhat depends on your platform). On Windows, it's  
quite easy to send MIDI messages, although latency may be an issue.   
(The Mac OS X Java VM does not make MIDI available to apps, so you  
need some additional software.  See http://www.mandolane.co.uk/ for  
more info.)

Below is some example code that sends a scale from MATLAB via MIDI:

import javax.sound.midi.*
scale = [60 62 64 65 67 69 71 72];

info = MidiSystem.getMidiDeviceInfo;				% This will return a list of  
available MIDI devices
outputPort = MidiSystem.getMidiDevice(info(2));		% The actual device  
index will vary depending on your configuration

outputPort.open;
r = outputPort.getReceiver;
note = ShortMessage;

for i=1:length(scale)
	note.setMessage(ShortMessage.NOTE_ON, 1, scale(i), 127)
	r.send(note, -1)

	pause(0.5);
	note.setMessage(ShortMessage.NOTE_OFF, 1, scale(i), 127);
	r.send(note, -1)

	pause(0.5);
end

outputPort.close;


Hope this is helpful!
