dump matrix factors to a file

[andreagalle]

Is it possible to write/output the matrix factors to a file in order to save time later on restarting my simulation?

In my case I just have to factor the matrix once, per case, but restarting the simulation many times I waste lot of resources factoring every time the same matrix.

I was looking for serialising/deserialising the matrix factors, but I was wondering if (hopefully) there was already an internal call, within the library, to do that!
