Hello,
I am trying to optimise a function using the GAMULTIOBJ tool, the function takes a 12x1 input vector and returns a 2x1 output vector, the input vector is the variables of the optimisation and the output are the goals that its trying to minimise. The problem is any time I try to run the optimisation the goals are negative numbers, I need to ensure that they stay positive. How do I put constraints on the goals alone but leave the input vector unconstrained?
Many thanks

If you have R2014b or later, use a nonlinear constraint function. Use one nonlinear constraint for each objective function. To save time, after debugging your constraints, you might want to use the technique in Objective and Nonlinear Constraints in the Same Function.

As I stated in my original answer, if you have R2014b or later, then yes, gamultiobj accepts nonlinear constraints. Otherwise, no.
