Quick followup question - When solving Ax = b, I have an outer loop that keeps 
feeding the same A matrix to the KSP solver, but with different initial guesses 
for x. When doing this, I get slightly different eigenvalue estimates every 
time (minimum real part off by 10%). I just want to confirm that this is 
because of the iterative process.

Thanks
