Details:

I'm using Ubuntu 12.04 64 bits

After downloaded the file(102.4MB)
http://aquarius.ime.eb.br/~apolin/CorpusCAEx2011/OriginalSignals/300m_MicArray1/50.mat
octave> load "50.mat"
octave>  plot(x(:,:))
Verifying gnome system monitor by processes and sorting by RAM usage, can see
three resource hungry processes:
-gnuplot using 2.4GB
-gnuplot_x11 using 1.5GB 
-octave using 247.8MB 

Cannot plot this other whole file(223MB):
http://aquarius.ime.eb.br/~apolin/CorpusCAEx2011/OriginalSignals/300m_MicArray1/FAL.mat
It causes memory leak. Just can plot parts of this file.

There is no problem with the .mat files, for they have worked with both
windows and linux matlab version, consuming much less RAM in both systems.
