Moving standard Deviation and Average

how would I go about finding the moving standard deviation and moving average for every 15 rows of the SPEED COLUMN ONLY in the following matrix and display the results in another table?

If you want to slide the 15 element window along an element at a time, use movmean and movstd.

If you want to move in "jumps" of 15 rows at a time, then you can either subsample the output of those functions or use blockproc in the Image Processing Toolbox. Or you can use a simple for loop:

% Compute speed over "blocks" of 15 elements
speed = t.Speed; % Get speed values from your table.
index = 1;
for k = 1 : 15 : numel(speed)
    meanSpeeds(index) = mean(speed(k : k + 14));
    index = index + 1;
end

Use movmean and movstd.
