This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.
Запускаю на Arch (3.16.4-1-ARCH), то же самое сообщение вываливается на поддерживаемой mathworks ubuntu 14.04 LTS.
Вероятно, следует отметить, что libmwservices.so была патчена добрыми дядями-пиратами (возможно, криво.).
Идеи?
inb4: R, scikitlearn не могут в машинку на разреженных матрицах. Octave просто не может.
