<div dir="ltr"><div><div><div><div><div><div>Dear all,<br><br></div>I was looking through the matdyn program wherein the dynamical matrices are calculated at any q-point through Fourier interpolation and I came across the wsweight subroutine.<br>
<br></div>I know that this subroutine calculates the weight factors that are used in the Fourier interpolation formula.I tried calculating the dynamical matrix at a point (0 0.6667 0, say) without using the weight factors and interestingly, I found that the values of the dynamical matrix obtained through matdyn do not match with those calculated directly.<br>
</div><div><br></div>I would like to know, what is the purpose/logic of this subroutine, since I see that this is an essential part in calculating the dynamical matrices at arbitrary q-points.<br><br></div>I would be grateful if you could shed some light on this problem.<br>
