<p><b>Solve nonlinear equation</b></p>
<p></p>
<p>Octave can solve sets of nonlinear equations of the form</p>
<pre>
F (x) = 0
</pre>
<p>using the function fsolve, which is based on the MINPACK subroutine hybrd.
</p>
<p>Given function, the name of a function of the form f (x) and an initial starting point x0, fsolve solves the set of equations such that f(x) = 0. </p>
<p>If function is a two-element string array, the first element names the function  described above, and the second element names a function of the form j (x) to compute the Jacobian matrix.</p>
