The FortranCalculus (FC) compiler calculates partial derivatives on the fly
. All a user does is enter their math equations & an objective (function)
and FC finds the optimal solution for the given problem. The FC compiler i
s free (download and use) at least for the next year or two; see http://for
tranCalculus.info/apps/fc-compiler.html .

FC can solve Algebraic thru Differential equations while 'tweaking' paramet ers. FC uses Automatic Differentiation (AD) to calculate either the jocabi an or Hessian matrix on the fly. Thus it is easy to use (next thing to a s lide rule!) and exact. Most problems require a math model (i.e. your equat ions) and just a handful of other misc. code. Try it, you'll like it.

Our textbook, http://fortranCalculus.info/textbook , has many (40+) FC examp le problem from industry. See and run other examples in fc-compiler's demo section. These demos examples can easily be modified to create one's own problem ... an hour or two and you should have solved your problem. :)

Please share FC with your colleagues, students, and friends. Knowing FC wil l help future students get jobs in industries that include math modeling.
