Good question. I am also highly interested in answers before buying Muse and MatLab.
I believe it will work with the new SDK v2 version, since MusePlayer (Phyton script) is now available and has an option to convert Muse data to MatLab.
I spent my full day yesterday looking for the tools available for MatLab and I was impressed with EEGLAB open source from SCCN Institute for Neural Computation based in the UCSD University of California San Diego - http://sccn.ucsd.edu/eeglab/index.html
I would give it a try, given the team names, the open source nature and the big comunity of contributors involved with new add-ins toolboxes.
I would also like to know if there are plans to support the Arduino plataform (bluetooth serial I/O for the ATMEGA microprocessors) like NeuroSky has in it’s Developers Tools.
Thanks a lot,
