<p><a name="index-structure_002dbased-configuration-settings-100"></a>
The vector-based settings <code>lbound</code>, <code>ubound</code>, <code>fixed</code>,
<code>diffp</code>, <code>diff_onesided</code>, <code>fract_prec</code>, and
<code>max_fract_change</code> can be replaced by the setting
<code>param_config</code>. It is a structure that can contain fields
corresponding to parameter names. For each such field, there may be
subfields with the same names as the above vector-based settings, but
containing a scalar value for the respective parameter.
<p>For example, if the parameters are named <code>a</code> and <code>b</code>, instead
of specifying
<pre class="example"> settings = optimset ("lbound", [-Inf; 0],
"diff_onesided", [true; true]);
</pre>
<p>one can specify
<pre class="example"> pconf.b.lbound = 0;
pconf.a.diff_onesided = true;
pconf.b.diff_onesided = true;
settings = optimset ("param_config", pconf);
</pre>
<p>If <code>param_config</code> is specified, none of the above vector-based
settings may be used.
