MATLAB: Compute Std with a time interval of 60sec

arraystandart desviatonstdtime samples

I have an array representing a time sample with 691200 points(the time frequency is 8Hz so each 8 points represent 1sec and the total array 1 day). I wanna compute the std of this array with a time window of 60sec. How can i do that?

How you approach this depends on what you want to do.
If you have R2016a or later, you can use the movstd (link) function to take the standard deviation of a moving window of 480 samples.
If you want to take the std of 480-sample discrete ‘blocks’ of your data without overlap, use the reshape (link) function.
I leave the actual coding to you.
