If you want to load all data at once, you need to extend the physical
memory and use a 64bit Operating system and 64 bit Matlab.

If you want to load pieces of data, you can use biosig's functions
sopen, sread, sclose. sread allows you to read segments of data into the
matlab workspace. I cannot say how well eeglab can handle this.
