Once the user has evaluated FX = f(X), the user may accept this approximation to the root, or else call the zero finder again, passing the just-computed value of FX so that it can take another bisection step. From then on, the zero finder repeatedly returns a value X, asking the user to evaluate the function there. To use the reverse communication zero finder, the user defines the values of A and B, and sets a parameter JOB to zero to indicate that this is the first call. Reverse communication instead allows the user's calling program to retain control of the function evaluation. This is sometimes an awkward formulation to follow. In the following table, each line/entry contains the program file name, the page number where it can be found in the textbook, and a brief description.

The problem statement, all variables and given/known data The purpose of this program is to calculate the approximate roots of the Sine function on given intervals. Many zero finders require that the user define f(x) by writing a function with a very specific set of input and output arguments, and sometimes with a specific name, so that the user can call the zero finder, which in turn can call the function. This routine is in part a demonstration of the idea of reverse communication. The routine assumes that an interval is known, over which the function f(x) is continuous, and for which f(a) and f(b) are of opposite sign.īy repeatedly computing and testing the midpoint, the halving change of sign interval may be reduced, so that either the uncertainty interval or the magnitude of the function value becomes small enough to satisfy the user as an approximation to the location of a root of the function. BISECTION_RC - Nonlinear Equation Solver Using Bisection, with Reverse Communication BISECTION_RC Nonlinear Equation Solver Using Bisection, with Reverse Communication BISECTION_RC is a FORTRAN90 library which demonstrates the simple bisection method for solving a scalar nonlinear equation in a change of sign interval, using reverse communication (RC).
