[Wavepacket-user] Version 7.1.0 of WavePacket (Matlab/Octave) released (02-Mar-2023)

[Burkhard S. <bur...@fu...>]

Dear friends of the Matlab version of WavePacket,

this is to announce the release of version 7.1.0 ([Git hash value 5e104a9d...](https://sourceforge.net/p/wavepacket/matlab/git/ci/5e104a9d1ea88a370c25cd95b2a877740e190198/)) which provides a number of minor fixes and useful extensions as detailed in the following list of tickets:

* [#232](https://sourceforge.net/p/wavepacket/matlab/tickets/232/):  Iso-surface plots for 3D-wavefunctions
* [#276](https://sourceforge.net/p/wavepacket/matlab/tickets/276/): Auto-detect Git version hash value
* [#277](https://sourceforge.net/p/wavepacket/matlab/tickets/277/):  Symmetric Euler scheme
* [#278](https://sourceforge.net/p/wavepacket/matlab/tickets/278/):  Components of electric field
* [#280](https://sourceforge.net/p/wavepacket/matlab/tickets/280/):  Code for Lyapunov solver
* [#281](https://sourceforge.net/p/wavepacket/matlab/tickets/281/): Sparsity and cutoff in qm_bound
* [#283](https://sourceforge.net/p/wavepacket/matlab/tickets/283/): Empty potentials, dipoles, etc ...
* [#285](https://sourceforge.net/p/wavepacket/matlab/tickets/285/): Settable initial momenta
* [#286](https://sourceforge.net/p/wavepacket/matlab/tickets/286/): Convergence in imaginary time

Note that our work on [#278](https://sourceforge.net/p/wavepacket/matlab/tickets/278/)  now allows for an arbitrary number of polarization directions, i.e. an arbitrary number of components of E-field vectors and dipole moments as well as polarizabilities. Unfortunately, this leads to a tiny **backward incompatibility**: Now the E-field amplitude must be given as a scalar or a row(!) vector; previously a polar represention in 2-D (amplitude and polarization angle) was used.
Another minor backward incompatibility is due to renaming class +efi.inter → +efi.interp, for consistency with classes 'interp' in package folders +pot, +dip, etc.

Best regards from Berlin/Germany
Burkhard
