SMALLbox

h1. 2012 Hack Session Notes

h2. Using SMALLbox Add-ons 

These are the steps needed to interface SMALLbox add-ons to the core SMALLbox distribulation:

# Download the add-on distribution from: http://code.soundsoftware.ac.uk/projects/incoherentdl/files

** The version you wish to download is *version 1.1*

** unzip the downloaded file - this will create a folder named @incoherentdl-v1_1@

# Place the add-on code in any convenient location of your file system, and add this to your MATLAB path

** @addpath(genpath('@{incoherentdl-v1_1}'))@

# Modify the relevant files in the folder @{SMALLBox Root}/config/@

** modify or create @{SMALLBox Root}/config/SMALL_learn_config_local.m@

*** @cp {SMALLBox Root}/config/SMALL_learn_local.m SMBOX/config/SMALL_learn_config_local.m@

**** this local file is not tracked by Mercurial 

**** if you need to revert to the _default_ SMALLbox setting, you just need to delete/rename your local file

*** add the following code to the local config file: 

<pre>

elseif strcmpi(DL.toolbox , 'SMALL_incoherentDL')

  DL=SMALL_incoherentDL ( Problem , DL ) ;

   % we need to make sure that columns are normalised to % unit lenght .

  for i = 1: size(DL.D,2)

    DL.D(: ,i)=DL.D(: ,i)/norm(DL.D(: ,i));

  end

  D = DL.D;

</pre>

# Run the @SMALLboxInit.m@ script to set environmental variables

# Run any function or script contained in the add-on.

** example: 

*** @load test_mocod.mat@ 

**** located in @incoherentdl-v1_1/results/test_mocod.mat@ (but already in path)

*** @open SMALL_test_mocod.m@

**** located in @incoherentdl-v1_1/open SMALL_test_mocod.m@

*** run the code from the block that starts on line 110 (with the comment Plot Results)

**** this will display two coherence/signal to noise ratio plots based on results previously computed
