Dear all;
I am trying to solve a MOOP using the Matlab global optimization toolbox. some of the parameters used in the objective functions are learned from table loaded from an excel file. when I run the code from the optimization toolbox it gives me an error "Subscripted assignment dimension mismatch." Please someone can help me about this. you can find attached the code.

Hi Walter, thank you for your comments. attached the excel file and a copy of the error. the data of P are:
lower: [1 0.45 1e-2 0.07e-3 1e-2 1] upper:[1e5 0.9 500e-2 7e-3 20000e-2 1000]

Hi Sobhi,
Thank you for providing the data and fitness function for reproducing this issue. One issue I am encountering right away when running this is that your fitness function currently returns a 2x2 matrix. Because of this, I am receiving the following error:
"Error running optimization. Your fitness function must return a scalar value."
In order to get this to eventually work, you will need to modify your fitness function so that it returns a scalar value instead of a matrix. I do not know more about the specific problem or fitness function you are working with, so I cannot provide much help in terms of how to fix this. Hopefully this at least points you in the right direction.
- Matt
