8-connected neighborhood curvature of a digital elevation model

File Information
Description	curvature returns the second numerical derivative (curvature) of a digital elevation model/surface. It distinguishes between profile and planform curvature. Profile curvature is the 2nd derivative along the steepest downward gradient. Planform curvature is the 2nd derivative perpendicular to the downward gradient.
Required Products	Image Processing Toolbox
MATLAB release	MATLAB 7.5 (R2007b)
