Hi,

I am trying to calculate the distance covered by a footballer in a ten-minute game. I have 3000 x-coordinates and 3000 y-coordinates in a 3000 by 2 matrix. Does anyone know how I can compute the distance covered?

Thank you

Ben

This would be my approach:

x = randi(99, 1, 100);                                  % Create Data
y = randi(99, 1, 100);                                  % Create Data
d = hypot(diff(x), diff(y));                            % Distance Of Each Segment
d_tot = sum(d);                                         % Total Distance

I tried this method and it produces a matrix of all possible distances between all stated points, which is cool unless one wanted to use a large data set, and only needed the first column or would crash the computer.
