teqp is a library written in C++ that allows for calculation of numerical derivatives of thermodynamic equations of state with respect to the independent variables with numerical differentiation tools. No hand-written derivatives are required, and the computational speed is competitive with, or better than, the results from hand-written derivatives in low-level programming languages.
