<div>Sorry , </div>
<div>i then checked the calculation of version 3.1.1, and didnot come to such error.</div>
<div>Maybe this error is only in Version 3.0.</div>
<div> </div>
<div>I should move to the latest version.</div>
<div> </div>

<div> Dear all,</div>
<div> </div>
<div> I wanna obtain phonon spectrum of the irreducible BZ, then i tried to run $(espresso)/examples/example06.</div>
<div> But the code came to crash for matrix diagonalization error, and just gave alas.dyn0, alas.dyn1, alas.dyn2 files .</div>
<div> I then just changed the k_points in scf calculation from 2 points to mkgrid (4,4,4, 0,0,0), and the calculation can be finished sucessfully.</div>
<div> </div>
<div> so, i would like to know whether this error is due to math-lib or k-point setting in scf calculation ?</div>
<div> </div>
<div>Regards,</div>
