The fprintf command is used to write the inputs R, T, and P to the file. Note the 'w' flag indicates that the file is available to write to and any existing contents are flushed. The file C:\Temp\Input.dat is opened using the fopen command in MATLAB. The MATLAB function is called EESProperty the header is given below:įunction = EESProperty(R, T, P) To illustrate this capability, we will develop a MATLAB function that returns the specific volume, specific enthalpy, and specific entropy given the fluid, temperature, and pressure. This capability allows other programs to communicate with EES and direct its execution. EES can be started and directed to run a predefined macro file from most programs.
