Operations_Time{1}=[10 0 0 10 0 20 15;2 0 0 2 0 2 1];
Operations_Time{2}=[10 13 0 0 12 0 15;2 2.5 0 0 3 0 1];
Route{1}=[1 0 0 4 0 6 7];
Route{2}=[1 2 0 0 5 0 7];
total_operations=5
MakeToPart_Power=[12 7 4 6 12 6 8];
setupcost_ofParts=[2 4 3 2.5 3.5 2];
[r1, c1]=size(Route)
for i=1:c1
    E=0;
    for j=1:6
        if Route{i}(j)~=0
            E=E+Operations_Time{i}(j)*MakeToPart_Power(Route{i}(j))
        end
    end
    Energy(i)=E 
end

the desired objective is the * application of E on 1st row of Operation_time{i}* and another function value iterate on 2nd row of Operation_time{i}.for example 'F' runs for 2nd row of operation time with same valu of (i) F=Operation_time{i}*setupcost_ofparts

To loop over the rows of the matrix A you can use

for this_row = A.'

This will make this_row a column vector that contains one row at a time of A. You will only get the contents of the row, not any information about which row it is.

If you need information about which row you are processing then you should loop over row numbers and extract the content of the row using matrix indexing.
