Vehicle Network Toolbox provides functionality related to CAN database DBC files, such as

canDatabase, messageInfo, signalInfo to access a *.dbc file (CAN message and signals definitions)
canMessage, attachDatabase to create and decode message signals based on the definitions in a CAN database DBC file.

It is not currently possible to create or edit a CAN database DBC file with MATLAB.

This can be done with a free 3rd party tool, Vector CANdb++ editor:

Vector CANdb++ editor is installed with the demo version of CANalyzer / CANoe, which can be downloaded from the Vector website:
