A=rand(960,1);
A=reshape(A,240,4);
A_OUT=mean(A(1:40,:))

actually i m doing project regarding tsunami.....i need to collect tsunami data for 4 hours and each data will be taken for 15 seconds so for each minute i will have 4 data and for 4 hours 960 datas and i need to take average for first 10 minutes(i.e 40 data) in each hour and in second hour average of first 10 minutes and so on till 4th hour and i will get 4 average values and i need to apply those 4 average values in one formula that is Hp(t') = SUMMATION i=0 to 3 (w(i) H*(t-idt)) and weights is w(0) = 1.16818457031250 w(1) = -0.28197558593750 w(2) = 0.14689746093750 w(3) = -0.03310644531250 and the link for the above formula is (<http://www.ndbc.noaa.gov/dart/algorithm.shtml>) from this i will get Hp(t') value which is 961 value and again from 2 to 961 value i need to repeat the same procedure to get 962 value lik that we need to calculate for 5000 values , its like moving average ... for this process i need to create matlab code
