Hi,
I have a list of pixel's coordinates of 3D binary image (the list's dim: number of pixels to change x 3: the first column is the 'X' coordinate, the second is the 'Y' cooridinate and the third is 'Z' coordinate).
I would like to change each pixel in that list to hold the value of '0' (black color). how can I do it so it won't take too much time?
code examples would be appreciated! :)

I(m(:,1),m(:,2),m(:,3))=0;

Are most of the pixels changing to zero? How do you decide which pixels to change (how is your maxtrix formed)?
