Hi guys,

I want to optimize my model. i have properties like mc,lcc,rc,etc., i need to assign them to a optimisation variable "P" which should be in the form of vector.for example

P(1)=lcc;
P(2)=rc;
P(3)=mc;

i need to assign my properties in this way. Can anyone tell me how write them in a correct way in OOP?

Any suggestions are appreciated.

Thankyou.

在 MATLAB Online 中打开

P(1)=obj.lcc;
P(2)=obj.rc;
P(3)=obj.mc;

where obj is the instance variable

Thankyou for your quick reply isakson. if i write this way in properties it is showing an error.

Inputs:

P(1)=mc;

P(2)=lcc;

P(3)=rc;

outputs:

f

classdef Optimization
    properties
        P=optimvar('P',3)
    end
    methods(Static)
        function f=fit(P)
            objCore.mc=P(1);
            objCore.lcc=P(2);
            .
            .
            .
            f=ObjCore.mc*objCore.lcc;
        end
    end
end

This is the way my program is. The problem is when i want to assign these optimization variable as input.This program is to show you the syntax of my program. What should i denote in my properties. How to assign the inputs in my function was a problem. I think i explained a bit clear.

Thankyou.
