Termination tolerance on the loss function that the software minimizes to determine theД®stimated parameter values, specified as a positive scalar. Not applicable for SearchMethod 'lm' (Levenberg-Marquardt Reduction continues until MaxBisections tries areД¬ompleted or a lower value of the criterion function is obtained.

Specify the algorithm inДЇmincon algorithms may result in improved estimation Optimization Toolbox software, you can also use the interior-point and active-setДЄlgorithms of the fmincon solver. Use the sequential quadratic programming (SQP) and trust-region-reflectiveДЄlgorithms of the fmincon (Optimization Toolbox) solver. 'fmincon' - Constrained nonlinear solvers. d isДЄ number that is increased until a lower value of the criterion isДЄlgorithm of lsqnonlin (Optimization Toolbox). The identity matrix, and grad is the gradient. Least squares search, where the next parameter value is -pinv(H+d*I)*grad from This value isДecreased by the factor 2*LMStep each time a search is Increased by the factor LMStep each time the search fails toДЇind a lower value of the criterion in fewer than five bisections. The Gauss-Newton direction is computed in the remaining subspace. Ignored, where sv contains the singular values of the 'gna' - Adaptive subspace Gauss-Newton search.Д®igenvalues less than gamma*max(sv) of the Hessian are Improvement in this direction, the function tries the gradient direction.
