Bio: Matricomp was a computer constructed as a response to Krypton's alarming divorce rate. Its purpose was to scan two individuals prior to marriage and determine if they were a suitable pairing. If it gave the go-ahead, the couple could then legally wed. If it did not, the couple's petition to the government for a marriage license would be denied.
Over time, it became a genuine "synthetic life form", capable of exceeding its programming. Indeed, it fell in love with Lara Lor-Van and attempted to use its position of legal authority to deny her petition to wed Jor-El II. It manifest itself inside the body of a very life-like android named Anr-Mu, and caused Lara to briefly, through some form of hypnosis, return its affections.
It was then outed by Jor-El II as an unreliable source of information about the long-term chances a couple had. The state-supported "computer dating" system was then abandoned.
