Hi again, I have trouble carrying out this optimization procedure. I know that I should use penalty functions when I have a constrained problem. Does MATLAB implement any penalty? Is there any example on this method?!

The documentation deals with nonlinear inequality constraints. The underlying algorithm for the nonlinear constraint solver uses penalty functions, but you don't have to do anything special, such as write your own penalty.

Again, I do not understand you. Sorry.
Perhaps you have a linear constraint in the variables a(x). You can write that as a nonlinear inequality constraint.
Perhaps you have a linear constraint in x. You can use the A, b matrices to represent that constraint.
You might mean something else. In that case, feel free to ask again, but I am afraid we are not communicating well.

Hi again, thank you so much. I had linear inequality constraint in the variables a(x).So by writing them in nonlinear inequality constraint I can fix this.
Best regards,
