What Is Optimization Toolbox?

lsqnonlinalgorithm. See “Optimization Options” on page 6-8 for detailedinformation.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 set to 'on'.Use medium-scale algorithm when set to '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.
