    Reading op.2 files in Matlab works, but I got new troubles

    Hi everyone, I finally wrote a matlab code to read [M] and [K] matrix and it works pretty well. However, I don't know what (i,j) component represent in terms of ID node... Could anyone give me any clue?? I heard FEM codes reorder d.o.f in order to get band sparse matrix Thank you in advance.
