Is there any package to load .arff format file into matlab? The .arff format is used in Weka for running machine learning algorithm.
Yes, there are a few MATLAB interfaces for WEKA files on MATLAB File Exchange, I normally use this one: http://www.mathworks.com/matlabcentral/fileexchange/21204-matlab-weka-interface where you have a saveARFF() and a loadARFF() functions.
