The Matrix was an Anomaly map, created by Nick Cutter to predict the locations of upcoming Anomalies, using patterns of Anomalies that have already appeared from history based on mythological and legendary creatures appearances.
After an encounter with an Ammut-like Pristichampsus, Nick Cutter remembered his theory that ancient civilisations could have interpreted prehistoric creatures as mythological creatures, and as such decided to plot the dates of the myths appearances in history to try to predict upcoming Anomalies. He then arranged for Sarah Page to be hired by the Anomaly Research Centre so she could help him. (Episode 1.3, 3.1) Nick and Sarah started mapping out Anomaly dates using clear pipes to indicated where two dates an Anomaly intersected the timeline. Nick did not want to map on a computer as it was less tactful. (Episode 3.2)
Nick explained the purpose of the matrix to Jenny Lewis and warned Connor Temple not to touch the pipes if he did not want to alter the course of the entire universe. Later on, Nick made his first Anomaly prediction though he was unsure if the Anomaly would open soon or in 12 years, however the field team went to the Brooks house to check.
The next day, Sarah went to the British Library to research on mythical creatures such as the Qilin while Nick was laying under the Matrix thinking about the Anomalies. Sometime later, an Anomaly opened at the Brooks house proving the Matrix work, which Nick stated "Of course I was right".
Nick showed James Lester the Matrix but the latter interpreted it as modern art not the complicated time map it was. Later on, as Helen Cutter infiltrated the ARC building with her Cleaner Clones and a Clone of her husband Nick, she studied the Matrix and was amazed but upset that she and Nick had not worked on it together. Helen got the Nick Clone to detonate a bomb to destroy the ARC and the explosion severely damaged the Matrix (and most of the building). Helen then shot Nick, the only person who ever understood the Matrix, and he died in the Matrix room.
As the ARC was repairing the building and operations, Jenny visited the Matrix room and was shocked at the mess of pipes and whiteboard equations that was the Matrix. She saw Sarah in the adjoining room and asked her if the Matrix could be rebuilt. Sarah said she wouldn't even know where to start as Nick "kept a lot of things to himself". (Episode 3.4) By the time of the future Fungus incursion, the wreckage of the Matrix had been removed. (Episode 3.5)
A device from the future, only known as the Artifact was presumably created by an alternate future Anomaly Research Centre and had a much more sophisticated version of the Matrix in holographic form. (Episode 3.6, 3.10, Series 3)

- The Matrix included creature labelled Anomaly tags. Readable labels were:
- It was generally assumed by fans that the holographic matrix on the Artifact was in some way made/contributed to by Nick Cutter or via a computer version of the Matrix made before his death. However this has never been confirmed.
- The Matrix does not appear have enough detail to "accurately date Anomalies" and predict locations but was shown to predict the location and the exact opening time of an Anomaly.
- It is unknown how Cutter predicted the Brooks house Anomaly because he appearently did not know what mythical creature the Camo-Beast was in history and there for could not date the Anomaly.
