FCWin (tm) is a frontend program for Fortran Calculus (tm). 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.
