How to find bin mesh,edges and centres

i have given bin width and i am confused how should i find bin mesh bin edges and bin centres i have this code but its not working..

% Get the bin mesh. Put some extra space on the ends.
x_lim_left = 0;
x_lim_rght = +4;
%x_lim_left = -1;
%x_lim_rght = +12;

t0   = x_lim_left;
tm   = x_lim_rght; 
rng  = tm-t0; 
nbin = ceil(rng/h); 
bins = t0:h:(nbin*h+t0);       % <- the bin edges ... 
bc  = bins(1:end-1)+0.5*h;     % <- the bin centers ...

Do you have a picture or something? What is 'bin'?

"i have this code but its not working"

This doesn't give us any useful information. We can't run your code because we don't have vaules for at least one of the variables.

Something to do with histograms, perhaps?
