how can i get the average of group of rows in time series?

i have time series recording one point value every 1 second, i need matlab to calculate the average of each group of 60 points to get 1 minute value along the time series(not moving average). i think i can use peravg or accumarray functions but i don't understand how to use it, so if you please could help.

I might suggest a function I have posted on the FileExchange . It's called timeseries_indexer.m and it takes a time series as an input along with timestamps, labels, and a window and outputs the exact kind of average you are looking for.

In your case, your time stamps would be

    timestamps = [1:60:length(data)];

your labels would be

    labels = ones(size(timestamps));

and your window would be

    win = [0 59]; %to stretch from sample 1 to sample 60

Call it like so and watch the magic!

    mean_data = timeseries_indexer(labels,timestamps,win,data);
