Averaging of 8 successive values in array
Posted:
Sep 24, 2013 10:57 AM


I have my Value array which is for unknown number of values
Value = 78 74 77 75 75 78 75 77 76 81 76 92 98
I want to calculate the moving average of first 8 values (i.e (78 74 77 75 75 78 75 77)/8 =76.125) and need to store in Average 1st value and after i need to calculate next 8 values (i.e (74 77 75 75 78 75 77 76)/8=75.875 )and need to store in Average 2nd value
for this i wrote a program but its result showing only the first value of Value is average for entire series ....
avg=[]; i=1; for i=1:length(Value); Average=0; j=1; if j<=i+7; Average=Average+Value(j); j=j+1; end % if Average==0; % Average=Average/8; % end avg(i)=Average i=i+1; end
But I am not sure whether it?s a correct command to be used or not. I appreciate any comment that you give on first how to calculate.
thanks & regards
