How did The Matrix 4, Neo and Trinity come back to life?

The English title of The Matrix 4 Resurrections means resurrection, and the resurrection of Jesus means resurrection. The title is spoiler, and neo, who died to achieve human-machine peace in the third part, will be resurrected. In the fourth part, not only Neo is resurrected, but Trinity is also resurrected.

The Matrix is a logical science fiction film, not a fantasy film, and Neo and Trinity can not be revived by the protagonist's aura, but to conform to the setting of the whole film.

1. Neo's resurrection. At the end of the third part, Neo is copied by Smith in the sixth generation of Matrix, and the Machine Emperor recycles Neo's body, without explicitly stating Neo's life and death. My personal understanding is that Although Neo was seriously injured, his vital signs are still there. Onlookers believe that Neo is an "anomaly within an anomaly", which has extremely high research value and use value for the machine world, and began to repair Neo's body. If you are blind in both eyes, you will rebuild a pair of eyes; if there is a wound on the body, you will suture it. After Neo's body is healthy, he then integrates his consciousness into the matrix, completing Neo's resurrection.

2. Trinity's resurrection. Triniti's resurrection is more difficult to understand than Neo's resurrection. In the third part, although Neo's life and death are uncertain, Trinity is pierced by several cones on the way to machine city and dies on the spot. Trinity died in the real world, that is, she no longer has basic vital signs such as breathing and heartbeat. Even if it is possible to recreate organs and reconstruct blood, how can the heartbeat and breath be regenerated? It may only be understood as the brain hole of the movie.
