Thank you very much for your quick reply and i am sorry for not defining some variables. As i said i have a matrix 250x250, so i just assigned row (1...250) as ypix and column (1..250) as xpix, which stands for pixels. XC and YC are center of each circle (XC,YC). XC(1,i) and YC(1,i) are center for each circle (i=1:6, spot number): R is radius of circle. I want to do statistical calculation only for matrix elements inside each circle but i could not figure out how to take positions (x,y position) of all pixels included in each spot.
