 Octave's minimizer functions are designed to only pass one optimization
 variable to @code{F}, but parameter passing can be accomplished by defining
-an @ref{Anonymous Function} that contains the necessargy parameter(s).  See
+an @ref{Anonymous Functions} that contains the necessary parameter(s).  See
 the example below:

 fminbnd (f, 0, 2)

 Note that anonymous functions retain the value of parameters at the time they
 are defined.  Changing a parameter value after function definition will not
 affect output of the function until it is redefined:

 @group

 B = 4;
 fminbnd (f, 0, 2)
-@result 0.8562

 The function @code{humps} is a useful function for testing zero and
 extrema finding functions.
