I am working on LNG plant optimization and using Matlab and Hysys as optimization and process simulation software and I have interfaced them using a spreadsheet.
Now, Hysys calculates values of variables x1, x2, x3, x4 and send to MATLAB, which optimizes them and send back the values to Hysys.
The sum of these four variables should be equal to one, that is x1+x2+x3+x4=1, that is if value of x1 is reduced by MATLAB then the values of remaining variables should be increased to make the sum equals 1.
I am not figuring out a way to correctly write in MATLAB. How should I formulate it?
Looking forward to your help.
