how can i subscribe and read a simple Int8 data into matlab using ros4mat?

[GoogleCodeExporter]

i have been trying to subscribe to a topic publishing (integer or float type) 
by a node from Ros into Matlab. 

i have succeeded to launch the node and got it publish the data, but i still 
couldn't figure out which file to edit for the subscription from matlab side. 

using Ros Fuerte on Ubuntu 12.04, with M2012a (matlab 2012a)
