Where did you get this code? What leads you to believe that ROOM should exist in MATLAB?

Answer 1

[Walter Roberson]

ROOM appears to be http://www.pnas.org/content/102/21/7695 . I do not see any evidence that it was implemented in MATLAB.

I do see the article https://www.researchgate.net/publication/221695802_Dynamic_regulatory_onoff_minimization_for_biological_systems_under_internal_temporal_perturbations_BMC_Syst_Biol where they implemented their modified ROOM, D-RFBA in MATLAB. It is plausible that in order to compare their version to ROOM that they implemented ROOM as well, so it might be worth checking to see if they made their code available.
