How to solve Index exceeds matrix dimensions probelm ?

I am using ind2sub for connected component.but problem is that when i run multiple images and pass on each connected component into ind2sub function, it shows error. It is ok when i run only single image.But creates problem for multiple images. I dont understand what the problem is ? how can i solve it ?

ERROR: Index exceeds matrix dimensions.

Error in try5 (line 214) [yyy,xxx] = ind2sub(CC.ImageSize,CC.PixelIdxList{id});

What is the size of CC.PixelIdxList? And what is the value of id?

You are using a value of id that is greater than the number of connected components .
