## Description

Specifies the number of nonlinear equality constraint functions returned by the interface.

The `targets` specification provides the targets for nonlinear equalities of the form

and the defaults for the equality targets enforce a value of `0`. for each constraint

The `scale_types` and `scales` keywords are related to scaling of . See the scaling information under specific methods, e.g., method-*-scaling for details on how to use this keyword.
