I have 12000 x 12000 R(data class single) sparse matrix, and I want to find its eigen values and vectors, but I can't do it in matlab, it gives out of memory error by doing(adsbygoogle = window.adsbygoogle || []).push({});

[V D] = eigs(R)

and I am using 4GB RAM , online help suggested using ARPACK or ARPACK++ with C/C++. please any alternative means or suggestion on how to solve this will be greatly appreciated .
