I have a non-linear curve fit that I would like to add constraints to the parameters. For example I always want one variable to be positive and another to be between 0 and 1. With the deviation of the results, the values lie within that range.
Thanks Doug |

Such constraints are available in non-linear curve fit tool.
Make sure your NLSF dialog is not in basic mode, then select Options menu - Constraints.
You can set lower/upper bounds for evry variable.
Moreover, you can also add general linear constraints.
