Comment on ' Computational method for the quantum Hamilton-Jacobi   equation: Bound states in one dimension' [J. Chem. Phys. 125, 174103 (2006)]
  Some difficulties, both numerical and conceptual, of the method to compute one dimensional wave functions by numerically integrating the quantum Hamilton-Jacobi equation, presented in the paper mentioned in the title, are analyzed. The origin of these difficulties is discussed, and it is shown how they can be avoided by means of another approach, based on different solutions of the same equation. Results for the same potentials, obtained by this latter method are presented and a comparison is made.
