SEUIF97: The high-speed shared library of IAPWS-IF97

SEUIF97 is the high-speed shared library of IAPWS-IF97. It is suitable for computation-intensive calculations,such as heat cycle calculations, simulations of non-stationary processes, real-time process monitoring and optimizations. Through the high-speed library, the results of the IAPWS-IF97 are accurately produced at about 3 times computational speed than the repeated squaring method for fast computation of integer powers, 10 times than the math.pow() in the standard library of the C. The dll and so libraries for Windows and Linux(X86/X64): Windows32/64: libseuif97.dll; Linux64: libseuif97.so The binding APIs for the programming languages: Python, C/C++, Microsoft Excel VBA, MATLAB, Fortran, Java, C
