Hi, so I have some 2D data and I would like to make a histogram, I've seen that I can do that with hist3 function, but I would like to define edges for the bins, not just divide the data range into n bins of the same size. So I've made this code:

dD=(0:0.01:0.25);
diam=[1 2 3 4 5 10 15 20 30 40 50];
z=hist3([krateri_br(:,3) krateri_br(:,4)],'Edges',[diam dD]');

But every time I get an error:

??? Error using ==> hist3 at 132 Bin edges must be specified with a cell array containing two numeric vectors.__

Now, I've tried different combinations of parenthesis for edges vector, but nothing seems to work. I have a feeling that I'm making some elementary mistake, but cannot find it, so if someone knows how to solve this, please help.

Thank you in advance!
