StarCentroid:

Path: Imaging/Optics

% Finds the centroid given intensities on n pixels and their coordinates.
   This uses the point spread function method.

   Type StarCentroid for a demo which will draw the centroid and the 
   intensity map.

   Since version 11.

   Form:
   [x0, y0] = StarCentroid( i, x, y )

   Inputs
   ------
   i            (1,:)  Intensity
   x            (1,:)  x coordinate
   y            (1,:)  y coordinate

   Outputs
   -------
   x0           (1,1)  x centroid
   y0           (1,1)  y centroid
