I have a for loop that is supposed to find the sum of the vector. It works with most vectors except those with zeros, please help. the specific input i have trouble with is
an2 = findSum([5 5 5 0 0])
function [sum] = findSum(vector)
sum = 0;
a = 1:20;
for i = vector
sum = sum + a(i);
end
end

(Assuming it is necessary for you to use the for loop)
You want to calculate the sum of a vector, but why are you not using that vector or its elements for the operation?

Ran in:
You should of course never do it this way.
an2 = findSum([5 5 5 0 0])
an2 = 15
function result = findSum(vector
result=0;
for v_i = vector
result=result + v_i;
end
end
