For one body I am able to finf the index of point by clicking on it.

How to for two bodies

What index you want?

[Arvind Kumar Pathak]

Index of any point in matlab plot.

Means by clicking on any individual point, it gives the index no of that point which tells the position of that point in that matrix.

Read about knnsearch to get the indices of multiple points.

[Arvind Kumar Pathak]

How to implement knnsearch for two matrix at a same time.

Please provide some example. I have not use knnsearch before.
