COMSOL Script is a numerical computing and programming environment mainly used for interacting with finite element multiphysics models created by COMSOL Multiphysics (formerly FEMLAB). It uses a syntax similar to that of MATLAB and also includes a Swing (Java) based GUI builder for cross-platform applications (Windows, Mac, Linux, Unix).
In Version 3.5a of COMSOL Multiphysics, Comsol Script was removed. Interfacing COMSOL Multiphysics 3.5a from a script based environment now requires MATLAB from The MathWorks, Inc[1].
