T-MATS: Ambient, Cantera Library Block
This block translates environmental condition to gas characteristics: Alt, dTamb, and MN to Pressure, Temperature, Velocity, etc.. To utilize this block a Cantera object must exist in the workspace as a global variable named fs, which may be created with the Cantera importPhase command. The fs variable must include all Species defined in the file canteraload.m.
