Hi,
I was wondering if someone can teach me why ABINIT obtained 9 columns and 4 rows of values in the output below. I would also be grateful if you can teach me how ABINIT obtained those values. I know it's got something to do with the oscillator matrix elements and possibly the eigenvaalues from the KSS file but I'm not too sure. Thanks.
