Reference.Variables.hamilt.truncate

Class definition "hamilt.truncate" in MATLAB/Octave version of WavePacket

Energy range outside of which the potential energy is cut off. Each kinetic energy is also cut off if it exceeds e_max − e_min. Mainly of importance for the Chebychev propagator, see here. For the source code of the corresponding classdef see here.

Property	Explanation	Default
e_max	The potential is truncated above this energy value	+Infinity
e_min	The potential is truncated below this energy value	−Infinity
