gative input variable. Termination
occurs when the cosine of the angle between <I>fvec</I> and
any column of the Jacobian is at most <I>gtol</I> in absolute
value. Therefore, <I>gtol</I> measures the orthogonality
desired between the function vector and the columns
of the Jacobian.
<P>
<I>maxfev</I> is a positive integer input variable. Termination
occurs when the number of calls to <I>fcn</I> is at least
<I>maxfev</I> by the end of an iteration.
