Minimizing Functions and Finding Zeros
Setting Minimization Options
You can specify control options that set some minimization parameters using
an options structure that you create using the function optimset. You then
pass options as in input to the optimization function, for example, by calling
fminbnd with the syntax
x = fminbnd(fun,x1,x2,options)
or fminsearch with the syntax
x = fminsearch(fun,x0,options)
Use optimset to set the values of the options structure. For example, to set
the 'Display' option to 'iter', in order to display output from the algorithm
at each iteration, enter
options = optimset('Display','iter');
fminbnd and fminsearch use only the options parameters shown in the
following table.
options.Display
options.TolX
options.TolFun
options.MaxIter
options.MaxFunEvals
A flag that determines if intermediate steps in the
minimization appear on the screen. If set to 'iter',
intermediate steps are displayed; if set to 'off', no
intermediate solutions are displayed, if set to final,
displays just the final output.
The termination tolerance for x. Its default value is
1.e-4.
The termination tolerance for the function value.
The default value is 1.e-4. This parameter is used
by fminsearch, but not fminbnd.
Maximum number of iterations allowed.
The maximum number of function evaluations
allowed. The default value is 500 for fminbnd and
200*length(x0) for fminsearch.
