Software Listing of Author : "Rodney Thomson"

Acquires buffers of data from the system default sound card, calculates the power spectrum of the data and plots this along with the raw sampled data to screen. Useful as a quick and dirty (and completely uncalibrated) audio frequency spectrum analyser. Extends previous function (http://www.mathworks.com/matlabcentral/fil...?objectId=20541) into a Matlab Class. The GUI uses an instance of this class. See http://iheartmatlab.blogspot.com for a detailed run-through of the code and the programming techniques utilised.

An output socket that allows zero or more TCP client connections to be made. A separate thread manages the client connections allowing for multiple clients to connect and disconnect at any time. Not just for data communication but also useful as a debug output monitoring tool. Usage: output_port = 1234; output_socket = MatlabOutputSocket(output_port); % Write a string out output_socket.write(int8(sprintf('Hi there how are you?rn'))); % Write some raw data out output_socket.write(rand(4, 'single')); % close socket connection output_socket.close(); For more details and an explanation of the Java helper class see: http://iheartmatlab.blogspot.com/2010/06/n...put-socket.html

Provides an example Server / Client written in MATLAB that utilises the ability to call Java inline to perform message communication using TCP/IP. Importantly it does not require any pre-compiled DLLs or force you to compile some MEX c-files. Nor does it require any additional toolboxes Its all contained within the .m files. To use the example: - Start 2 instances of MATLAB - in the first execute the following: message = char(mod(1:1000, 255)+1); server(message, 3000, 10) - in the second execute the following: data = client('localhost', 3000) For more details see: My Webpagehttp://iheartmatlab.blogspot.com/2008/08/tcpip-socket-communications-in-matlab.html
