<p><a name="index-minimization_002c-providing-a-function-to-minimize-2261"></a>
You must provide a continuous function of one variable for the
minimizers to operate on. In order to allow for general parameters the
functions are defined by a <code>gsl_function</code> data type
(see <a href="Providing-the-function-to-solve.html">Providing the function to solve</a>).
