function s = sumUp(X)
%Simple function in MATLAB.
% s=sumUp(x) is a function that returns s given s=Sigma(X(i)).
% Caution! X here is a vector: X=[ x1 x2 ... xn].
s = 0;
% ============= YOUR CODE HERE ==============
% Instructions: Return s given s=Sigma(X(i)), X is a vector.
% Use built-in function length(X) to obtain the length of X.
% Use for loop to sum up all elements of X.
% ===========================================
end

Thank you, for that. One of the examples shown solved it, but I need to clean it up a bit.

Try the following code.
function s = sumUp(X)
s = 0;
for s=1:length(X)
s = s + X(s);
end
end

It doesn't output, the required info. Thank you for the effort, and the script is right. I believe I found the solution.

He should not have had s be both the accumulating variable and the loop index. It should be:
function s = sumUp(X)
s = 0;
for k = 1 : length(X)
s = s + X(k);
end
end

I discovered it was the right script, but a few letters needed to be changed inside the statement after looking at the documents and noticing one of them used a different identifier. I am new to this style of scripting, but it's been fun so far! Thank you!
