At least first 7, but I also need the eigenvectors as well, I have inquired about mathematica, I discovered I have to change the matrix R ( which is generated in matlab) into its format manually (quite impossible for a 12000 x 12000 matrix) which means there is not command that can easily do...

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 [V D] = eigs(R) and I am using 4GB RAM , online help suggested using ARPACK or ARPACK++ with C/C++. please any...
