[BangPypers] Multiplying very large matrices

Hi all,
while implementing Locality Preserving Projections ,
at one point i have to perform X L X.transpose()
these matrices are large (32256 x 32256) so i get "out of memory" error.

I assume, as the dataset gets larger one would come across this problem ,
how would
one go about solving this ? Is there a common trick that is used to deal
with such problems ?
Or the workstation calculating these problems needs to have HUGE  amounts of
physical memory ?

I am using python and numpy / scipy
