What Is Optimization Toolbox?

lsqcurvefitmedium-scale algorithm. You can use optimset to set or changethe values of these fields in the options structure options. See“Optimization Options” on page 6-8 for detailed information.The LargeScale option specifies a preference for which algorithm to use.It is only a preference, because certain conditions must be met to use thelarge-scale or medium-scale algorithm. For the large-scale algorithm,the nonlinear system of equations cannot be underdetermined; that is,the number of equations (the number of elements of F returned by fun)must be at least as many as the length of x. Furthermore, only thelarge-scale algorithm handles bound constraints:LargeScaleUse large-scale algorithm if possible when setto 'on'. Use medium-scale algorithm when setto 'off'.Medium-Scale and Large-Scale AlgorithmsTheseoptionsareusedbyboththemedium-scale and large-scalealgorithms:DerivativeCheck Compare user-supplied derivatives (Jacobian) tofinite-differencing derivatives.DiagnosticsDiffMaxChangeDiffMinChangeDisplayDisplay diagnostic information about the functionto be minimized.Maximum change in variables for finitedifferencing.Minimum change in variables for finitedifferencing.Level of display.
