Extracting overlapping windows of data for analysis

Hi all, I have an array of data points and I need to analyse overlapping windows of that data. i.e. I have 30000 data points and first want to extract the first 1024 data points (data points 1-1025), analysis it and save the answer of the analysis. Then I want to analyse the next window of data with an overlap of 2 (data points 1023-2047) and have that answer of analysis saved with the previous answer. I am quiet new to Matlab and I have no idea where to start with this. Any help would be much appreciated. Many thanks.
