D4M is a library accessed through Matlab. You must be familiar with Matlab before using D4M. To use D4M on the MSI lab machines, load the matlab module and add the following lines to the top of your Matlab input, or in your startup.m file.
D4M_HOME = '/nfs/soft-el6/d4m/2.0.3' % SET TO LOCATION OF D4M.
addpath([D4M_HOME '/matlab_src']) % Add the D4M library.
Assoc('','','') % Initialize library.
If you have an accumulo database, you can access it from Matlab by defining a connection, e.g.
DB = DBserver('accumulo1:2181','Accumulo','msitest', '','')
