I have a speed and time trace from which I'd like to calculate the average running speed, i.e. the average speed taking into account only the non-zero speed values.
Any ideas? Many thanks in advance.

I’m not certain how you want to calculate average speed, but this is one approach that uses only the non-zero speeds:
time = 0:0.1:10; % Create Data
speed = randi([0 9], 1, length(time)); % Create Data
nz_idx = speed>0; % Logical Vector Of Non-Zero Speeds
avg_speed = cumsum(speed(nz_idx)) ./ time(nz_idx); % Average Speed Of Non-Zero Speeds
