Hi,
I have this line of code "tracks = findTracks(vSet)" which tracks points in multiple views and save it in tracks both the points coordinates and their viewid. I need to extract the points coordinate from the tracks object but I don't know how?!!! when I run tracks.points in workspace it will show each points coordinates in different images as s single matrix. somthing like this:
ans =
2×2 single matrix
1.0e+03 *
3.7766 1.8622
3.7599 1.8431
ans =
2×2 single matrix
1.0e+03 *
3.7776 2.1873
3.7574 2.2002
however, I need to extract all points in an array but I could't. btw the code is part of this implementation:

If anyone know how to do this please let me know. Thank you

Hi,
It’s my understanding that you are trying to extract all the point coordinates from tracks into a single array. Following is the code for the same:-
allPoints = vertcat(tracks(1:end).Points);
