How to select 11×11 cells on image?

I have matrix of 10 selected pixels with x,y coordinate(in column), say 10×2 matrix A. have to take each pixel as a center of cell, so have to select 10 cell. I need matlab coding.

You have described your inputs: a matrix of 10 2d coordinates, and presumably an image.

You have not explained at all what you want has an output. What does select even mean? Point at it on the screen?

my image is binary image. I selected 10 pixel randomly from image. I want to give white color to the cell.
