Has anyone used gPROMS to simulate distillation towers?

Has anyone used gPROMS to do distillation tower simulation calculations? I would like to discuss it with experts!
Many people in the forum have done this, ask your questions!
Has anyone used state equations and tridiagonal matrices to calculate composition in gPROMS?
If you want to discretize algebraic equations into matrix equations and solve them, MATLAB has more advantages.
I know this, but MATLAB is not as good as gPROMS for solving equations!
However, gPROMS logical operations are not as flexible as MATLAB! Welcome experts who know gPROMS to come in and discuss!
gPROMS is a dynamic simulation software. When it comes to valve switching, flow rate changes, and PID control, it is feasible and convenient to use it. However, the distillation process is a steady-state process, and the gas-liquid composition at each equilibrium stage is unchanged. There is no need to use gPROMS, not to mention that the gPROMS language is more complicated than MATLAB. The balance equations of each stage of the distillation process are combined into a matrix equation. There is no need for complicated programming in MATLAB. It should be more convenient to solve it with MATLAB than the former.
I know this, someone in our laboratory has already calculated it using MATLAB! But as I said, MATLAB is not easy to use when solving a large number of differential algebraic equations. Especially when the tower is very complex, MATLAB's shortcomings are extremely difficult to overcome!
