MATLAB: If the input is 3 we want the output to be 1 2 1

inputorder

Can someone please help me figure this out, this is part of a bigger code. If the input is 3 we want the output to be 1 2 1. If the input is 5 we want the output to be 1 2 3 2 1 and so on.The input could be any odd number 3,5,7,9… Thank you in advanced and please let me know if you have any questions. Follow up : I am trying to create n point symmetric weighted moving filter, without the use of filter function. I attached an image of my approach. (I can't figure out how to upload the excel file)
time=xlsread('ECG','A:A')
  amp=xlsread('ECG','B:B')
  N=length(time)
  for i=2:N-1 %3 point  filter
      t(i-1)= (amp(i-1)+2*amp(i)+amp(i+1))/4;
  end
  for i=3:N-2%5 point filter
      t2(i-2)=(amp(i-2)+2*amp(i-1)+3*amp(i)+2*amp(i+1)+amp(i+2))/9
  end
  %My approach for n weighted filter:
  n=input('enter point: ');
  k=  floor(n/2);
  for i=k+1:N-k
  weights=[1 2 1]%if the input was 3
  x(i-k)=(amp(weights.*(i-k:i+k))/sum(weights);
  end

Best Answer

Shouldn't it be just,
 >> n = 7;
 >> weights = [1:ceil(n/2) floor(n/2):-1:1]
 weights =
    1   2   3   4   3   2   1
