The Matlab CAPE-OPEN Unit Operation is a unit operation implementation for which the calculations can be entered in Matlab. The Matab unit operation functions in CAPE-OPEN compliant simulation environments that support version 1.1 thermodynamics or version 1.0 thermodynamics (requires Matlab 7.1+). It has been tested in COCO simulator, SciSci ProII, AspenPlus, Honeywell Unisim Design and other simulators. Requires Matlab version 5.3 or higher
