so, i was trying to get the value of entalphy and entrophy using REFPROP (for my multiobjective optimization), here the code: t5 = 6+273; %in kelvin. p5 = refpropm ('P','T',t5,'Q',1,'r407c.mix'); h5 = refpropm ('H','T',t5,'P',p5,'r407c.mix'); s5 = refpropm ('S','T',t5,'P',p5,'r407c.mix');

Matlab calls refprop (64-bit environment) and physical property instructions, Programmer Sought, the best programmer technical posts sharing site.

You need few files. which you can download from Refprop files -Link : https://trc.nist.gov/refprop/LINKING/Linking.htm#MatLabApplications.Refprop Google driv We would like to show you a description here but the site won’t allow us. MATLAB Applications. Keith Wait from GE Home Business Solutions has made the following MATLAB application available. This application calls the Refprop DLL directly rather than through the mex file provided in previous versions of Refprop. New Features of REFPROP Version 10 Enhancements have been made to most areas of the NIST REFPROP program, including the nist-equations of state for many of the pure fluids and mixtures, the transport nist-equations, the graphical interface, the Excel spreadsheet, the Fortran files (i.e., core property routines), the sample programs in Python, C++, MATLAB, VB, etc.

To avoid The database can be REFPROP, an industry standard developed by NIST, or the open-source CoolProp. The tables are stored in fluidTables as a structure array. A liquid substructure contains the data for the Liquid Properties tab and a vapor substructure contains that for the Vapor Properties tab. New Features of REFPROP Version 10 Enhancements have been made to most areas of the NIST REFPROP program, including the nist-equations of state for many of the pure fluids and mixtures, the transport nist-equations, the graphical interface, the Excel spreadsheet, the Fortran files (i.e., core property routines), the sample programs in Python, C++, MATLAB, VB, etc.

I encountered a problem when calling Refprop software using Matlab. In this code "result = refpropm (prop_req, spec1, value1, spec2, value2, material1)", the first or second input character (spec1

Unfortunately, because there is no charge for the mini-Refprop software, we are not able to provide technical support due to the limited number of staff available at NIST in the thermophysical properties division. Support is available only with the full version.
