Warp matrix
A warp matrix, or warp control system, was the interrelated series of systems responsible for a vessel's faster-than-light propulsion system.

In 2154, while trapped aboard a Romulan drone ship, Commander Charles Tucker was able to locate the vessel's warp matrix and disable the main coupling, successfully deactivating the ship's warp drive. ()

Later that year, 's warp matrix was compromised by a Klingon subroutine, which infiltrated the ship's command protocols. The subroutine locked open Enterprises antimatter flow regulators, causing the plasma pressure in the intermix chamber to rise uncontrollably, forcing the crew to increase their speed to dangerously high levels, until Commander Tucker was able to perform a manual shutdown and restart, successfully purging the subroutines from the matrix. ()

In 2374, the core matrix aboard Sisko's attack ship was "fried" after being caught in the explosion of a Dominion ketracel-white facility, rending the ship warp incapable. ()

In 2375, upon deciding to accept a position at Starfleet Academy as a Professor of Engineering, Deep Space 9's chief of operations Miles O'Brien joked with Dr. Julian Bashir that "somebody has to teach you officers the difference between a warp matrix flux capacitor and a self-sealing stem bolt. " ()

In 2377, while briefing  Torres on the status of the , Lieutenant Paris noted that the warp matrix was out of alignment by 0.3 microns. ()

Later that year, while engaged in combat with the , Ranek, captain of a Lokirrim warship, tied his ship's shields directly into the warp matrix, gambling that the Voyager crew would not willingly open fire, an act which would trigger a core breach. ()

In 2383, the young crew of the abandoned  encountered a tachyon storm that interfered with the proto-drive's gravitational balance, fracturing time and threatening to cause a warp core breach. In order to stabilize the core and restore the ship to normal time, the crew had to work together across disparate timelines to build a new warp matrix and install it before the ship exploded. ()

In an alternate timeline in 2390, the  experienced an overload in its warp matrix, the result of battle damage with the , which ultimately resulted in the Flyers destruction due to a core breach. The timeline in which these events occurred was eventually negated when Harry Kim was able to send a message back in time, averting a disaster which destroyed Voyager in 2375. ()
