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.
