The INonLDVariable interface contains properties and methods that are used to work with the variable included into the system of non-linear equations.
| Method name | Brief description | |
| CoefficientsOrderForestall | The CoefficientsOrderForestall property determines an order of coefficients for expected values. | |
| CoefficientsOrderRetrospective | The CoefficientsOrderRetrospective property determines an order of coefficients for initial values. | |
| Constraints | The Constraints property returns variable constraints. | |
| ControlVariable | The ControlVariable property determines whether this variable is a controlling one. | |
| Forestall | The Forestall property determines expected values of variable. | |
| Id | The Id property returns variable identifier. | |
| InitApproximation | The InitApproximation property determines an array of initial approximations for variable. | |
| Name | The Name property determines variable name. | |
| Retrospective | The Retrospective property determines initial values of variable. |
