How to use Aspen Plus – Matlab Link?
Please help me I am new to Matlab and Aspen Plus but have basic knowledge so please guide in detail. Please tell me what steps do I follow to link Aspen file and Matlab.
The Matlab cod file is:
%% Created by Ing. Andrés Felipe Abril. Universidad Nacional de Colombia. Departamento de Ingeniería Química.
%% Linking
Aspen = actxserver(‘Apwn.Document.36.0’); %34.0 —> V8.8; 35.0 —> V9.0; and 36.0 —> V10.0

Aspen.Visible = 1; % 1 —> Aspen is Visible; 0 —> Aspen is open but not visible

%% Example of Application
Reflux_Ratio = [1, 3, 5, 7];

Aspen.Engine.Stop;
end
