Hi
I have the attached coords_17 array, which is 2092 x 3 dimensional. Within this array, I want to find say the row which contains the coordinates [44, -30, 54]. However, the following commands fails somehow:
find(coords_17 == [44, -30, 54])
How can I find the relevant coordinates correctly? Many thanks

I would use the ismember (link) function.

Try this:

target = [44, -30, 54];
Lidx = ismember(coords_17, target, 'rows');
row_number = find(Lidx)
row_number =
     2
