Extracting groups of vector

Hello,

i would like to extract subvectors of a vectors. I ask me, if this is possible without loops or so. I have a data, that is shown below. Lets say the y-axis is a vector A and the x-axis B. As you can see there is groups of points along the x-axis. I would like to extract all columns that you can see in the picture in subvectors. The selection needs to be with a tolerance, since B is a measured data.

Do you have any idee, how this could be done? thank you in advance!

Read about ismembertol, knnsearch, kmeans. More help on explaining the question clearly with data.

You could try running clusterdata on the x-axis coordinates.

Nice - I didn't know about that function. I was going to suggest histogram or histcounts, which would also work.

If you didn't have the stats toolbox, you probably would have to resort to that.
