Hello, Iam trying to make a sum of numbers going from just the first number all the way to the 1st+2nd+3rd+...+last number.
Iam getting error "Index exceeds the number of array elements. Index must not exceed 1." and dont know what Iam doing wrong.3
This is the code I have so far.
x = load('ceny.txt');
x = sort(x);
x_pocet=numel(x);
for i=1:x_pocet
trzba = sum(x(1:x_pocet(i)))
end
"ceny.txt" is just a document with random numbers ranging from 1 to 1000.
