This article pretty much explains the Matrix addition to DJI's offerings. I assume based on this that the Matrix-100 is just the first in this family.
Key quote:
"How will DJI keep its drone hardware business from being commoditized by cheap knockoffs? By fostering a drone operation software developer ecosystem with a new $75 million growth equity investment from Accel Partners.
DJI may build variations of its drones for agriculture, oil & gas, mining, and other commercial tasks. But to make sure its drones can handle a much wider variety of use cases, it wants to invite developers to create software to customize its drones for niche use cases. The DJI platform could keep customers locked in to it drones rather than going with whatever’s cheapest."
