Hello, I have a matrix of time series data as attached. Time series lengths from 1970-2012. I need to extract moving block of 30-year window from this, with moving a year on every-time step. For example, the first block from 1970-2009, 2nd block 1971-2010, 1972-2011, and so on.
so something like this:
for i=size(unique(matrix(:,1),1)
30_yrblock = [my timeseries]
do whatever calculation with 30-year window
Result(i,:) = [];
However, I am not sure how to do so. Any help please?

Use the movmean function with the SamplePoints option. See the "Sample Points for Moving Average" example on that documentation page.
Alternately if your data is stored in a timetable use the retime function.

Thanks but I am not calculating moving average. I need a 30-year moving window.
