Reference.Variables.plots

Variable "plots" in MATLAB version of WavePacket

This global, structured(!) variable contains a plethora of parameters that control the appearance of the various plots and movies that WavePacket can create (mostly on the fly, i.e., while the simulations are running). For a simple explanation, see also the Users' Guide

Densities

WavePacket can visualize time evolving densities, calculated either as absolute squares of wavefunctions (see class "wave") or obtained by binning trajectory data (see class "traj") in many different ways. The corresponding field "plots.density" can be an object of one of the following classes defined in the "+vis" package folder:

class	description	dimensionality
densities	generic classdef (superclass): all classdef's below inherit from this one	n.a.
curve	curve plots	1D only
polar	polar plots	1D only
contour	contour plots	1D (Wigner) and 2D
surface	surface plots	1D (Wigner) and 2D and 3D
flux	probability fluxes	1D and 2D
scatter	scatter plots (trajectories only)	1D only ¹
reduced_1d	reduced densities in each dimension	wave: up to 5D ¹ traj: any number
reduced_2d	reduced densities in pairs of dimension	wave: 2D and 4D ¹ traj: any even number

¹ Extensions to higher dimensionality available upon request

Expectation values

WavePacket can visualize expectation values of the most important observables, either calculated from wavefunctions (see class "wave") or from trajectory bundles (see class "traj"). The corresponding field "plots.expect" has be an object of the following classes defined in the "+vis" package folder:

class	description
expect	visualization by various curve plots

Spectra

WavePacket can visualize absorption spectra, calculated as Fourier transform of wavefunction autocorrelation (see class "wave"). The corresponding field "plots.spectrum" has be an object of the following classes defined in the "+vis" package folder:

class	description
spectrum	visualization by curve plot

General settings

By default, the density and the expectation values are plotted with reasonable default settings. However, in case of very special requirements you may want to overwrite some of them though. There is a plethora of variables to tweak even the minor aspects of plot creation, such as font names, line widths, window sizes etc. Below, we are trying to give a complete description.
