Next nearest coordinate from a point in alist of coordinates

prathaban durai

Hi,

I have a list of coordinates say {(100,30),(120,70),(300,400),(90,80),(50,60),(389,700),(690,1000),(450,300),(900,100),(1100,680)} etc

I have sorted the list with x coordinate.. to start with a least point.

I need to find next nearest point from a given point say (100,30).. how to find it ? any suggestion.. do we need to find distance between two points that is nearest and compare the distance ? any idea? Thanks in advance :)

Yes, you would have to calculate all distances between your start coord and all other coords. If you need to do this for more/all coords, you might be better off creating a distance matrix in advance.

The distance between two points is the square root of delta x squared plus delta y squared.
