what exactly is your x above? is it a matrix? struct array?
cell? you show values with a "," in it, so confusing to guess
what you have.

You have to start with describing the data stucture your data
is in. Be clear what is it. If it is a matrix of 3 columns,
each column for a coordinates, then writing

x(i,:) gives you the 3 coordinates in the i'th row as a vector.
