**fsolve_test**,
a Python code which
calls fsolve() which
seeks the solution x of one or more nonlinear equations f(x)=0.

Note that fsolve() is available in scipy.optimize.

**fsolve_test** is available in
a MATLAB version and
an Octave version and
a Python version.

bisection_rc, a Python code which seeks a solution to the equation F(X)=0 using bisection within a user-supplied change of sign interval [A,B]. The procedure is written using reverse communication (RC).

test_zero, a Python code which implements test problems for the solution of a single nonlinear equation in one variable.

zero_rc, a Python code which seeks a solution of a scalar nonlinear equation f(x) = 0, using reverse communication (RC), by Richard Brent.
