Adding number in a sequence

How do i make a code,where I have to add the previous numbers to next numbers in a sequence. I used a for loop

for jj=0:13

x=jj

this code gives me the value of 0 to 13.right?

but I need to add all the terms with a previous term . what can I do?

"what can I do? "

Nowhere in your code do you actually add anything.

If you want to add numbers, then you should think about which numbers you need to add, and then try adding a + into your code in the location that makes the most sense. Experiment!

n=[1:15]

while n==isprime(n)

for n=1:15

for jj=0:16

x=(n+jj)^(99/100)

end

end

end

thats what I have done so far,,but I need to add the values of x with each other. when i run the function i only ge6t the name of the file on the command window ,,no output except for the array of n in 1st line

I have absolutely no idea what you're attempting to do with that code. It doesn't make any sense.

i only ge6t the name of the file on the command window ,,no output except for the array of n in 1st line

That would be because the while condition is not true to start with. So the code inside the while is never executed and only the first line has any effect.

Note that isprime return either 0 or 1. So if n is scalar, n == isprime(n) will definitively be false for any n different from 0 or 1. And since isprime is 0, the only n value for which n == isprime(n) is true is n = 0. But also note that your n is a vector.

movsum(jj,2);

what does the 2 do in that function? I am new to matlab,,so i am having hard time putting these all togteher. also it said for the value of n=-13, x should be 63.6

You can lookup the function. Matlab has great descriptions.
