How can I get the number of values within a range?

Hi, I am trying to get the number of values within a range, but this range is moving. For example, I have a value a as the center of my range. So I define my range as a+std. So I get how many values are within such a range. Then I move the range by a shift, such as my new range si (a+shift)+std. The next range will be (a+2shift)+std, and so on. What I have in my code is the following:
lo_edge=center_range-std;
hi_edge=center_range+std;
bunchcenter=center_range;
kk=0;
while bunchcenter<colum_of_int(end)
kk=kk+1
bunchcenter=center_range+kk*shift;
number_values= colum_of_int>=lo_edge & column_of_int<=hi_edge;
end
I would be thankful to have some help.

so what is the question? is your code not working? if so please describe the results you get and the desired result you would want. Also, if you can, share the data as well

Your code is almost correct. You just need to update the values of lo_edge and hi_edge inside the loop to reflect the new range. Here is the updated code:
lo_edge = center_range - std;
hi_edge = center_range + std;
bunchcenter = center_range;
kk = 0;
while bunchcenter < colum_of_int(end)
kk = kk + 1
bunchcenter = center_range + kk * shift;
lo_edge = bunchcenter - std; % update lo_edge
hi_edge = bunchcenter + std; % update hi_edge
number_values = colum_of_int >= lo_edge & colum_of_int <= hi_edge;
num_values_within_range(kk) = sum(number_values);
end
Hope it helps :)

Note - Do not use the names of inbuilt function as names for variables. It is not a good practice. Either capitalize std or better, rename it completely.
