%description
This is designed for use with an arbitrary set of equations with an
arbitrary set of unknowns. The user selects "fixed" values for enough
unknowns to leave as many variables as there are equations, which in most
cases means the system is properly defined and a unique solution exists.
The function, the fixed values and initial values for the remaining
unknowns are fed to a nonlinear backsolver. The original version of
"TK!Solver" , now a product of Universal Technical Systems
(<https://www.uts.com>) was the inspiration for this function.
