Use find() on the second column of the matrix with the 'first' option, then use that index to return the corresponding value in the first column of the matrix.

   X = randi([5 20],10,2);
   I = find(X(:,2)>10,1,'first');
   X(I,1)

I just created some data to illustrate how to do it since I don't have your data and that is easier than me copying off your figure. I just created a 10x2 matrix of random integers between 5 and 20 with that. You don't need that line, you only need the lines:

I = find(X(:,2)>10,1,'first');

X(I,1)

but obviously, you need to use the name of your matrix.
