[FieldTrip] Error: Undefined function 'mxSerialize_cpp'

["Jörn M. Horschig"]

Hi Vitoria,

hope you're enjoying Berkeley ;)
I assume the same error will occur for more people in a bit. We'll 
discuss it in the next FT meeting tomorrow. In the meanwhile, check this 
out (I responded to Sara last week, who got the same error):
