>> help optimset 'optimset' is a function from the file C:\Octave\Octave-4.2.0\share\octave\4.2.0\m\optimization\optimset.m -- optimset () -- OPTIONS = optimset () -- OPTIONS = optimset (PAR, VAL, ...) -- OPTIONS = optimset (OLD, PAR, VAL, ...) -- OPTIONS = optimset (OLD, NEW) Create options structure for optimization functions. When called without any input or output arguments, 'optimset' prints a list of all valid optimization parameters. When called with one output and no inputs, return an options structure with all valid option parameters initialized to '[]'. When called with a list of parameter/value pairs, return an options structure with only the named parameters initialized. When the first input is an existing options structure OLD, the values are updated from either the PAR/VAL list or from the options structure NEW. Valid parameters are:
AutoScaling
ComplexEqn
Displayは、デフォルトオフなんだ。
Display Request verbose display of results from optimizations. Values are: "off" [default] No display. "iter" Display intermediate results for every loop iteration. "final" Display the result of the final loop iteration. "notify" Display the result of the final loop iteration if the function has failed to converge.
FinDiffType
FunValCheck
When enabled, display an error if the objective function
returns an invalid value (a complex number, NaN, or Inf).
Must be set to "on" or "off" [default]. Note: the functions
'fzero' and 'fminbnd' correctly handle Inf values and only
complex values or NaN will cause an error in this case.
