+## @item ComplexEqn
+##
+## @item FinDiffType
+##
+## @item FunValCheck
+## When enabled, display an error if the objective function returns a complex

+## @item GradObj
+## When set to "on", the function to be minimized must return a second argument
+## which is the gradient, or first derivative, of the function at the point
+## @var{x}.  If set to "off" [default], the gradient is computed via finite

+## @item Jacobian
+## When set to "on", the function to be minimized must return a second argument
