Let say the example below
x=(10,20,30,40,50,60,70)
which mean
x(1)=10;
x(2)=20;
x(3)=30;
...
x(7)=70;
How can i define the variable using loop without mentioning or defining one by one ?
As i have x(1) up to x(1155) so I can sum x(1)+x(2)+...+x(1155)

x = 10:10:70 ; % this will generate [10,20,..70] ;
sumx = sum(x) ; % this will give you sum of array
Also you can call each number from array by indexing.
for i = 1:length(x)
xi = x(i)
end

I could really use the answer to this question if anyone found out how to do this. I am having the same exact problem in my code currently

I suggest that you start a new question with details. I cannot understand why the previous answers suggesting to use sum are not adequate, so more detail is essential to get a helpful answer.
