Our verdict
Scilab is a free numerical computing environment used in many Indian engineering labs as a MATLAB substitute. It includes Xcos, a block-diagram simulator similar in spirit to Simulink. Its language is not MATLAB-compatible, so scripts need rewriting. Version 2027.0.0 was released on 15 October 2026.
