I have wrote some MATLAB code, using some parameters from genetic algorithm input to EES for calculating thermodynamic properties. Then I get the calculated result and output from EES to matlab. But I met some problems, the connecting MATLAB code as attach file.

Because I have bought the academic version EES software, I input the parameters into EES by writing parameter value in dat file, and EES got the data from dat file. However, the calculating process stopped in the EES interface, no command have executed after that. If the program runs successfully, EES should return calculating results to MATLAB within seconds.

I have no idea what wrong with it, can anyone help me? I can't thank you enough.
