Hi,
I'm interested in the internal workings of the sparse and full diagonalization programs, because I want to parallelize and adapt it to my studies.
Could someone point out to me the code section in which the Lanczos is performed, especially the parts where a)preconditioning according to lattice symmetries, and b)reorthonormalization
is done? (I'm a newbie at C++)
Also, I can't find the source code which corresponds to the fulldiag_mpi binary in the fulldiag tutorial directory. Would someone show me where it is, or kindly link me to it, if possible?
Much appreciation is due from me! (I'm doing an undergrad research project) Shao
