We are pleased to announce QuTiP version 2.2.0, which now is available for download at the project's web page:
http://code.google.com/p/qutip/wiki/Download
Some of the many changes in this release include:
New Features
- Added Support for Windows
- New Bloch3d class for plotting 3D Bloch spheres using Mayavi.
- Bloch sphere vectors now look like arrows.
- Added partial transpose function.
- Added continous variable functions for calculating correlation and covariance matrices, the Wigner covariance matrix and the logarithmic negativity for multimode fields in Fock basis.
- The master-equation solver (mesolve) now accepts pre-constructed Liouvillian terms, which makes it possible to solve master equations that are not on the standard Lindblad form.
- Optional Fortran Monte Carlo solver (mcsolve_f90) by Arne Grimsmo.
- A module of tools for using QuTiP in IPython notebooks.
- Increased performance of the steady state solver.
Bug Fixes
- Function based time-dependent Hamiltonians now keep the correct phase.
- mcsolve no longer prints to the command line if ntraj=1.
We would especially like to thank everyone who has contributed with bug reports and code to this and previous releases of QuTiP!
