Tīmeklis2024. gada 7. febr. · This is a pre-release. QuTiP 5 is a redesign of many of the core components of QuTiP (Qobj, QobjEvo, solvers) to make them more consistent and more flexible. Qobj may now be stored in either sparse or dense representations, and the two may be mixed sensibly as needed. QobjEvo is now used consistently … TīmeklisTo help you get started, we’ve selected a few qutip examples, based on popular ways it is used in public projects. Secure your code as it's written.
