Hi

I am trying to connect RefProp(V9.1) to MatLab(V2016b). I have followed two guides ( Here from GitHub and Here from NIST). I have downloaded the files:

refpropm.m
REFPRP64.dll
refprop.h
REFPRP64_thunk_pcwin64.dll
rp_proto64.m

I have tried having them both in the RefProp directory and in a separate folder, but to no avail. I linked MatLab to the folders when I was testing. I always get the same error.

>> testVal=refpropm('T', 'P', 101.325, 'Q', 0, 'water')
Error using loadlibrary
Too many input arguments.
Error in ==>@()rp_proto64(BasePath) at 211
There was an error running C:\Program Files (x86)\REFPROP\refpropm.m.
Run @()rp_proto64(BasePath) from the command line to reproduce the error and fix it.
Error in refpropm (line 227)
    [notfound,warnings]=loadlibrary(strcat(BasePath,dllName),prototype,'alias',libName);
Caused by:
    Error using rp_proto64
    Too many input arguments.

Has anyone had the same error and solved it? Any suggestions?

Thank you for any help

@priyanshu chhabra , I experienced the same problem here. You should move the 'rp_proto64.m' to the same directory as your <working>.m file. Then try to run the <working>.m again. You should not experience the error again.
