Computing the Standard Deviation of Values in a column in Matlab

Say I have the following dataset:
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1365814/image.jpeg)
I would like to compute that standard deviation using ONLY SPEED values from ONLY 15 rows at a time in the table shown. How would I go about executing this in Matlab? Is there a specific code that can simplify this task?

I am assuming that you already have this table imported into matlab? If not use the read() command to do so.
Then first convert your desired column into an array and then use std to calculate the standard deviation
SpeedArray=table2array(Table(4,:));
StandardDeviation=std(SpeedArray(1:15));

out = std(tablename.Speed(1:15))

Isn't a "moving standard deviation" required, i.e. standard deviation of rows 1-15, 2-16, 3-17 etc ?
