creating array with specific condition

data= 689 x 1 
% moving average values for the last 50 data
data_average(1)= mean(data(1));
data_average(2)= mean(data(1:2));
data_average(50)= mean(data(1:50));
.
data_average(51)= mean(data(2:51));
data_average(52)= mean(data(3:52));
.
data_average(689)=mean(data(640:689));

How I can vectorize this computation?
