Thanks for this useful information, Dave.

May I ask you one more question? :-) To obtain full L-matrix of 
multiple signal strips in semiconducting dielectric stack the problem 
must be solved N times where N is the number of strips, each time 1A 
net current should apply to the next strip while keeping all other 
strips at zero net current. 
It means that we keep solving the same equation N times replacing 
only right hand sides.

Have you any idea how to make your iterative solver to memorize most 
of results from the initial solution and reuse them for the following 
solutions? Direct solver does this trick when it stores results of LU 
decomposition and reuse them for multiple RHS. 

Thank you,

Samuel
