FC-Win (tm) is a front-end 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.

Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. This is a Fortran Calculus demo application.

Robot4 (tm) is a Robotic Arm Movement program where the arm is moved from a given position to a desired position. The program finds the angles necessary for the desired position. Problem came from NASA. Robot4 is an Inverse Problem example. It wants to solve how to move from starting point `A` to target point `B`. Solutions to Inverse Problems are easy with the Fortran Calculus programming language. See `Rob4User.fc` file.

CurvFit (tm) is a curve fitting program 4 Windows 9x. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked/valleys data. CurvFit is an example of Fortran Calculus programming... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error). See comments in EX*.?

Calculus-level language used for solving this two point boundary value problem (BVP). The equations being solved may be ordinary differential equations and/or partial differential equations of any order & degree. Equations maybe nonLinear, implicit, any order, any degree and/or constrained. Automatic Differentiation (visit http://www.digitalCalculus.com/page/593538) coupled with Operator Overloading are the key ingredience for a Calculus-level programming
