There are set of scatter points with X and Y coordinates. I want to collect the points ( atleast a few points) which are located at the right most end of the plot.

I tried to use boundary() function and for each index provided by the function, to get to the right most point. It works if the start index of the boundary function is convinient.

Alternate logic without the use of boundary function is-

To consider each Y coordinate ( for example for i=0:0.1:1) in a 'for' loop and in that take the point with max X coordinate. and collect the X and Y coordinates in a new array. But I cant understand how to put that into a code.

I'm new to Matlab and any help or new logic will be really appreciated.
