Write Constraints

Provide bounds, linear constraints, and nonlinear constraints

How to express constraints for various problem types.

Functions

checkGradients Check first derivative function against finite-difference approximation (Since R2023b)

Types of Constraints
Choose the most appropriate form for your constraints.
Iterations Can Violate Constraints
Considerations for constrained problems.
Bound Constraints
How to write constraints for individual components.
Linear Constraints
Include constraints that can be expressed as matrix inequalities or equalities.
Nonlinear Constraints
How to include general inequality and equality constraints.
Checking Validity of Gradients or Jacobians
Check whether a derivative function matches finite difference estimates.
Or Instead of And Constraints
Optimize when only one constraint of a set is necessary.
Objective and Nonlinear Constraints in the Same Function
Save function evaluations, typically useful in simulations.
How to Use All Types of Constraints
Example showing all constraints.

Passing Extra Parameters
Including extra parameters or data in your objective or nonlinear constraint functions.
