Hi I want to print optical matrix elements (like in theTransmatrix in vasp 4.6) from the linear_optics.F. Could anyone tell me which variable do I have to print. Is it :
CHAM(m,n,NK,ISP,j)= <u_m|- i d/dk_j | u_n> = - <u_m| r_j |u_n>
! is returned
! where m and n are band indices
! j is a cartesian index
