Average running speed from time and speed trace

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
