Hello, based on the indexing used in your question, i think something like this could do:
% Assuming your matrix or vector to be: "t", having 150,000 rows
t;
% Assume the starting index for averaging 300 rows at a defined interval to be; "i"
i=1100;
% Set interval over which to average every 300 rows
interval=1460; % interval over which the start of the next 300 rows will be chosen
% Number of rows from your matrix or vector; "t"
nrows=length(t);
% Using a "for" loop
for k=1:ceil(nrows/interval)
if i+300<=nrows % this condition prevents averaging beyond the length of the array
avg_flow(k,1)=mean(t(i:i+300,:));
else
end
i=i+interval;
end
% Please note the length of "avg_flow" will determine the total number of intervals taken for a given starting index.
