MATLAB: Undefined operator ‘-‘ for input arguments of type ‘cell’.

handle_function

Hello I am trying to optimize a function and I defined the objective function as follow:
Tp=Scope{1,1}.values(2:36,7);
T1= Scope{1,1}.values(2:36,9);
To= cell(35,1);
To{1}=888;
   for i=2:36
       To{i} = @(k) To{i-1} + (k)*(T1(i)- To{i-1} )
   end 
obj=(sum(Tp - To).^2)
when running the function I keep getting Undefined operator '-' for input arguments of type 'cell'.

You can try to figure it out for yourself by checking some of the following things
  1. Dimensions of the arrays not the same
  2. The contents of the arrays cannot be used for mathematical operations e.g. strings
  3. To access cell content, you should use {} instead of ()
