Thanks flameout.

I can't do SciLab or R because I don't know how to use those

Just installed SciLab 5.4.1 with Intel Math Kernel Library 10.3 on a 7-year-old desktop PC:
- Intel Pentium D 3.4GHz (x86 Family 15 Model 6 Stepping 4)
- 32-bit XP Pro SP3
- 500GB Seagate Barracuda 7200
Code:
-->stacksize(70000000);
-->tic; N=read("N.dat",2509,2509); toc
ans = 1.672
-->d=read("d.dat",2509,1);
-->tic; x=N\d; toc
ans = 1.672
-->tic; Ns=sparse(N); toc
ans = 0.141
-->tic(); xs = umfpack(Ns,'\',d); toc
ans = 0.14
