Dear all,

With help of the community I discretized my data, x-coordinates of particles, into bins. For every bin I want to take the mean of all the x-coordinates that are in the bin. However, as time goes by the bins will be empty since the particles will move out of the bin to another bin. Thus, I can not use the function splitapply to group and take the mean of the x-coordinates in every bin. What can be an alternative for this problem?

for i = 1:length(files)
    ...
    % Define the range of the bins
    rng_x{i} = -0.3:0.06:0.3;
    % Assign the data of x-coordinate to a predefined range
    disc_x{i} = discretize(expData{i,1}(:,1),rng_x{i});
    ...
end
