Hello,

I need to compute the SVD of a large and sparse matrix: approximately, 7.7
million rows, and 20 columns with 10% non-zero elements. I will not need all
the eigenvectors; only the first 50 or so. Does anyone know of an existing
software or easily implementable algorithm which can do this?

I did some simple experiments for doing this on Matlab, but ran out of
memory everytime I tried.

Thanks
Fijoy
