out_mat_l given a irregular results when the atoms exceed 150. #6907
Description
Describe the bug
Dear developer,
I use out_mat_l to output the matrix L. However, when the number of atoms exceeds 150, the files Lx.dat, Ly.dat, and Lz.dat produce irregular results. Specifically, lines 10 and 11 become indistinguishable, and the last two lines exhibit the same issue.
In contrast, out_mat_l outputs regular, expected results for systems with a smaller number of atoms. For instance, the system in Figure 2, which contains 14 atoms, works correctly, while the system in Figure 1, with over 150 atoms, shows the described irregularities.
