Search for the Y coordinate knowing the X coordinate

Hi. Probably a trivial question.

I have a .txt file mx3 double.

A     % .txt file mx3 double

I want to determine the coordinate present in the figure (the outermost one to the right).

I started by determining the maximum value in the x direction by finding the coordinate.

coord_x = A(:,1);
X = max(coord_x);

How can I determine the value of y (-83.5175)?

How are the point represented in Matlab? Use the max() command for the x component.

[Alberto Acri]

The coordinates are in a .txt file (or point cloud)

[Voss]

coord_x = A(:,1);
coord_y = A(:,2);
[X,idx] = max(coord_x);
Y = coord_y(idx);
