Using find command to group data into bins

I have one ascii file with 2 columns (1st X and 2nd Y) .

I want to group the elements of X into bins (e.g. [2-4,4-6, etc) and I would like to group values of Y values based on the group of X values.

How could I use find command in order to make it?

Could you please help me?

I wouldn't try to use find. I would try to use discretize, findgroups, or histcounts (or maybe histcounts2) instead.

find is not the tool for this; see

grpstats or groupsummary or for more generality, findgroups combined with splitapply

If I have undersood your question correctly, in this case, find() is not quite efficient. Thus, you can better create just indxes, e.g.:

A1 = [X(2:4), Y(2:4)];
A2 = [X(4:6), Y(4:6)];

% OR:
XY=[X,Y];
B1 = XY(2:4,:);
B2 = XY(4:6,:);

[dpb]

group the elements of X into bins (e.g. [2-4,4-6, etc)"

Raises the Q? of just precisely does this mean? I and Chris interpreted as grouping by the values of X whereas Sulaymon's A assumes just on the index order.
