Hi,

I want to LinearSolve a square matrix (434160,434160) with sparse storage.

When I use SparseIterative with levelfill = 1, the commande gives a solution with very bad precision. I used many other options to get better precision without succes.

When I use SparseDirect (which I want to use), my PC (with 16G RAM) is bloqued and I must shut down it. 

Is any advices to use SparseDirect for matrix with high dimensions and sparse storage. 

Or, I must use another PC or another type of storage.

Thanks in advance.
