zero_muller is available in a Fortran90 version and a MATLAB version and an Octave version.
bisection, an Octave code which applies the bisection method to seek a root of f(x) over a change-of-sign interval a <= x <= b.
bisection_integer, an Octave code which seeks an integer solution to the equation F(X)=0, using bisection within a user-supplied change of sign interval [A,B].
bisection_rc, an Octave 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.
root_rc, an Octave code which seeks a solution of a scalar nonlinear equation f(x) = 0, or a system of nonlinear equations, using reverse communication (RC), by Gaston Gonnet.
test_zero, an Octave code which defines some test functions for which zeroes can be sought.
zero_brent, an Octave code which seeks a solution of a scalar nonlinear equation f(x) = 0, by Richard Brent.
zero_chandrupatla, an Octave code which finds a zero of a scalar function of a scalar variable, starting from a change of sign interval, using the Chandrupatla method, which can converge faster than bisection, regula falsi, or Brent's method, by Tirupathi Chandrapatla.
zero_itp, an Octave code which finds a zero of a scalar function of a scalar variable, starting from a change of sign interval, using the Interpolate/Truncate/Project (ITP) method, which has faster convergence than the bisection method.
zero_rc, an Octave code which seeks solutions of a scalar nonlinear equation f(x) = 0, or a system of nonlinear equations, using reverse communication (RC).
