The Fortran Calculus (FC) language is for math modeling, simulation, and optimization.

FC is based on Automatic Differentiation that simplifies computer code to an absolute minimum; i.e., a mathematical model, constraints, and the objective (function) definition.

Minimizing the amount of code allows the user to concentrate on the science or engineering problem at hand and not on the (numerical) process requirements to achieve an optimum solution.FC-Win has many (60+) example problems with output (see Demos) for viewing and getting ideas on solving your own problems.
