Comment on "HADOKEN: An open-source software package for predicting electron confinement effects in various nanowire geometries and configurations"

In a recent work [C. Chevalier, B. M. Wong, Comput. Phys. Commun. ${\bf 274}$, 108299 (2022); arXiv: 2203.05233 [cond-mat.mes-hall]] the interesting and popular problem was considered. Authors attempted to solve the self-consistent Schrödinger-Poisson problem for an effective mass electron in a core-shell semiconductor nanowire. The corresponding MATLAB-based software package was presented. However, an incorrect solution of the Schrödinger equation invalidates the whole result. Here we point out the corresponding error and possible ways to fix it.
