Hello everyone!

I have some data collected of the velocity of the wind. The duration is ca. 40s and in order for me to calculate the std and thus the intensity of the wind , I divided the signal into ca. 5 seconds. . (At first I did groups of velocity data of 5 sec,so u_segments would be [8x237568],there are 1900544 measurements of time)

First segment would be the velocties from 0-t1,second t1-t2,and so on. So for each 5s I get an std of the velocity. Std vector is 8x1.

Now I need to plot std - Intensity with time. How can I do it?

Thanks in advance!

First, you must pick a time representative of the averaging -- beginning, middle, end is up to you but once you decide then it should be easy enough to implement.
