Nested For Loop Equation

I have an array (N) filled with the 25 prime numbers between 1 and one hundred.

And I need to build the equation

x = (((((( (n)^ 99/100 n-1)^ 99/100 )+ n-2)^ 99100 ) +n-3)^99/100 )....+ 1 ^99/100)

and apply to every number in the array.

For example, the 6th prime number is 13, the equation would be

x = ((((13^(99/100)) + 12)^(99/100) +11) ^(99/100) +10)^(99/100)....+1)^99/100 = 63.6

I know this is going to need some sort of nested for loops create the equation.

for i = size(NN,2)  % For i = 25
    NN(i);
    for j = max(NN) % For j = 97
    ((NN(i)^(99/100))+NN(i)-j)^(99/100)
    end
end

This is my initial attempt, any guidance or help would be greatly appreciated.

Tis quick and dirty, but this work...

clear;clc;

N = primes(100);

newVect = zeros(size(N));

for ii = 1:length(N)
    tempSum = 0;
    for jj = N(ii):-1:1
        tempSum = (tempSum + jj)^(99/100);
    end
    
    newVect(ii) = tempSum;        
    
end

disp(newVect)

Update: I changed the variables to match your OP. I also cleaned up by adding preallocation.

As a side note, this seems like something you would want to put into a function... JMHO.

MATLAB provides a function for this kind of operation: fold()

Thanks for tip about fold(). I've never heard of it, but it does seem useful, especially for this application.
