Options for Iteration Control

Enter the optional variables in the edit boxes. Default values are obtained by leaving the space empty, or entering the word 'Default'. Press Apply to accept the variables as entered.
FixedParameter
A row vector containing the indices or names of the parameters to be kept fixed during the minimization. Default is no fixed parameters. The indices are discussed in the manual section Enumeration of Estimated Parameters. See also IDPROPS ALGORITHM.
Examples: [5,8,12] or {'A(1,2)','K(2,3)'}
Note the curly brackets for string parameter names.

The next three options are all described under Algorithm Propertis in the manual.

MaxIter
The maximum number of iterations to be performed. Default value 20.
Tolerance
When the expected improvement inthe criterion is less than Tolerance (measured in percent) the iteartions are terminated. Default value 0.01.
LimitError
Robustification of the quadratic criterion of fit. Residuals that are larger than LimitError times the estimated standard deviation carry a linear rather than quadratic weight. LimitError = 0 disables the robustification and gives a pure quadratic criterion.Default value 1.6.
