Constraint problem in Problem-based optimization live task

hi, i'm trying to optimized an equation where the data used was in matrix. it is succesful when there is no constraint but the moment i apply a constraint it error as follows;

i saw one similar problem and was suggested to use fcn2optimexpr, and it exist in the code of define problem objective but not in the define problem constraint, which i cant edit the code that came from the live task.

is there any solution on this? thankyou

Notice that when you assign to problem.Constraints, you are asking to execute constraintFcn with those parameters, and the constraint that should be stored into problem.Constraints is whatever is returned by the constraintFcn.

Perhaps you need to use https://www.mathworks.com/help/optim/ug/fcn2optimexpr.html

thankyou for your answer. from the link that you send, does it mean i need to code the optimization & the constraint from the start instead of relying on the live editor task? sorry im still new to matlab :)

I have never used the Live Editor task for optimization, sorry.

no problem, thankyou.
