Hi, In the following link: https://in.mathworks.com/matlabcentral/answers/889452-how-to-get-brushed-data-point-index-from-plot How do I use the pos function? Any specific toolbox I should have? It does not work for me (unrecognised function or variable).

Can you give a link to this function ? I cannot find it.

@Torsten - do a search on the FEX for pos. I did, but there are many possible candidates. My best guess is the kinematics TB, since many students seem to be doing kinematics lately.

Now that we see what is meant by pos, we see that in fact, pos is just an array. It is not a function at all.

In that post, pos was just presumed to be a list of the coordinates of a set of points in a 3-dimensional space.

Ran in:
which pos
'pos' not found.
We cannot tell you how to use a function that does not exist in MATLAB.
Is pos a function that would be found on the file exchange? Maybe. A short name like that may have been used multiple times,
Maybe it is a function from the kinematics toolbox.

Should we know? How?
Mybe it is found here:
https://www.mathworks.com/matlabcentral/fileexchange/60974-murphy-diagrams?s_tid=srchtitle
We cannot possibly know which function among many you are thinking about. Or possibly it is a function you or someone you know wrote.

Sigh. In the post you show, Pos is just an array. It is not a function.
