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

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

test_nonlin, an Octave code which implements test problems for the solution of systems of nonlinear equations.

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

- fsolve_test.m calls all the tests;
- fsolve_test.sh runs all the tests;
- fsolve_test.txt the output file;

- fsolve_test01.m applies fsolve() to some scalar nonlinear equations.
- fsolve_test02.m applies fsolve() to some systems of- nonlinear equations.
- timestamp.m prints the YMDHMS date as a timestamp;
