The thermo Matlab object lets the user calculate all thermodynamic properties as functions of temperature T and molar volume v, or of T and pressure p. All partial derivatives of the Helmholtz free energy up to order 3 are available, letting the user create analytical jacobians for efficient solution of most problems.

Documentation notes and user guide as well as examples and demo scripts are included. Any feedback is most welcome!

Uses the same model and parameters as NIST (
