a = randi(10,1,6);
b = randi(10,6,1);
c = randi(10,6,4);
d = randi(10,4,3);
e = randi(20,20,1)-10;

MATLAB has a builtin sum function. To get acquainted with loops, pretend
you could not use that function, and instead recreate the result using a
for-loop.
Create a variable that will hold the result and initialize it with 0.
Then iteratively add each element of the vector to the result. You can
check your result with the builtin function.
i=[a b c d e];
for j=1:length(a) -1
sum1(:,j)= a(:,j)
sum_iter(:,j) = sum1(:,j)+ sum1(:,j+1)
j=j+1
end
How can i know what is the last element in sum_iter? I am not sure if I have 7 column in a datasets. This loop is only for a data sets. Thanks

Hi Vimal,
You may access the last element of a matrix using the end keyword.
Hope this helps.
