How to count each element in array

in my case, i have an array enveloped in for loop

for i = 1:6
array = [0.5 1 5 2 7 3]
end

now i want to show the result of sum in array element (ex: 0.5 + 1 on first iteration, then 1.5(result of previous iteration) + 5 and so on)

the code that i already try is :

array(i) = array(i) + array(i-1)

but i can't get the result. i already tried with temp, but the problem persists.

thank you

Note that each iteration of that "for i" loop, you are overwriting all of array

thanks for the answer!

my first programming language before MATLAB is C#, and apparently C# use recursive for my case (already worked it with my friend).

in C# (for example)

for(int i = 0: i<7; i++)
{
    new_array[i] = old_array[i] + old_array[i+1];
}

*it's 7, because c# starts counting from 0

i'm still confused with MATLAB array element, how to express if we want to add array(i) with one element before it(i-1)

[Walter Roberson]

What you had before

array(i) = array(i) + array(i-1)

should work, provided i starts at 2.

... But you need to be sure not to overwrite all of array in the loop. The assignment to array should not have been in a loop.

thank you! i really appreciate it

Are you just interested in this?

array = [0.5 1 5 2 7 3];
sum=cumsum(array)

If you just want add two neighbouring terms, this should work:

sum= array(1:end-1)+array(2:end)

which basically adds an element with previous one.
