I have a for loop and I want it to calculate the mean of sum of square of elements of an array, in a fixed-length period;
The array is b (1 by 30). the segments that I want to calculate the mean(sum(square(b))) are 3 by 3 steps: for example first calculate it for the first 3 elements. then calculate for the second three elements, and so forth.
Now the problem is this loop doesn't work for all i and j values. it only calculates for the last i an last j.
Please guide me with this. thanks in advance
here's the code:
