15.3.4.4.9 The Bounds and General Linear Constraints Page

This page offers options to allow you to specify lower and/or upper bounds for each parameter. This page is optional, so you can directly click the Next button to go to the next page to perform other settings. And please note that you can also specify these values in the Nonlinear Fitter dialog during the fitting session.

Note that it is only possible to use the general linear constraints when the function model is set to Explicit.

Dialog Box Controls

Bounds Group	Offer controls to allow you specify lower and/or upper bounds for each parameter. Lower Bounds Specify the lower bounds for parameters. It can be edited only when < or <= has been selected from < or <= column. < or <= Double click the cells in the operator column (< or <=) to choose a proper operator. Then enter the lower or upper bound values in the respective edit boxes. Param List the all the fitting function parameters' names. Upper Bounds Specify the upper bounds for parameters. It can be edited only when < or <= has been selected from < or <= column.
Use General Linear Constraints	Check this check box if you wish to specify linear constraints on parameters. Separate multiple lines by semicolon.
General Linear Constraints	Allow you to input linear constraints for the parameters. You could also specify the constraints in the Nonlinear fitter dialog during the fitting session in General Linear Constraints. The following is an example of linear constraints. a > b; a + 2 b >= c * 2 ? d;* a < b < c; a / 3 < 9;
