How to combine Refprop with Matlab 2015b version?

Hi all,

I have built a Matlab program in version 2015a. The program is combined with Refprop interface. It runs perfectly when I use Matlab 2015a, but when I try to run my program with Matlab 2015b I get this error:

Error in refproparray (line 101) eval([string1, string2]).

It seems that there is something wrong when combining 2015b version with Refprop. Has anyone had the same problem? Any ideas what goes wrong?

By "Refprop" do you mean the "NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP)"?

What is the FULL text of the error message (all of the text displayed in red?)
