Hi Maurizio,

Unfortunately the read(byte []) method will not work directly from within MATLAB. My thoughts as to why:

When you execute:
  data = zeros(1, 100, 'char');
  data_input_stream.read(data, 0, 100);
It supplies a COPY of the data array which would be populated. Unfortunately you don't have access to this. This requires pass-by-reference semantics which I don't think MATLAB currently support.

To get around this issue personally I've created helper Java classes to read blocks of data and RETURN the Byte array. This requires creating Java classes and compiling them.

Email me if you want some examples.

Hello! I have one question.. Can i send wav files through this? Or this is only to send messages?
Thanks for your help

It's very useful to build a simple network with MatLab, but in the example you read abyte in a loop. I've tried to read the buffer with the method read (byte [ ] b, int off, int len) of the class DataInputStream, but I don't find anything into the buffer b; the result of this method (the of bytes read) is correct! How can I pass the input buffer to the method?
