Dear Rik, dear maintainers,

Cristiano Dorigo worked with SOCIS and the official end of programme is 
tomorrow. He worked a lot with pcg, gmres, bicg, bicgstab, cgs fixing 
several errors, bugs, incompatibilities and not always clear 
documentations. 
For better compatibility, he changed some output diagnostic (value of the 
flag error, number of iterations) and also the result itself (for 
instance, when the methods reach the maximum number of iterations, Matlab 
returns the best approximation, aka with minimal residual, not the latest 
as Octave does).

I followed him weekly, I think he made a great job, but honestly it is 
quite hard to me to make a deep review (maybe alone) of all his work in 
the next six days. And a deep review is needed, since he touched almost 
all the iterative methods for linear systems. Is it possible to have more 
time for the review? Anyone else would like to help me in the review? Is 
it possible that we introduce in 4.2 only the new pcg and gmres (probably 
the most used solvers, and the first two Cristiano started to study and 
modify)?

Thanks,

Marco
