Websurfnorm (X,Y,Z) creates a three-dimensional surface plot and displays its surface normals. A surface normal is the imaginary line perpendicular to a flat surface, or perpendicular to the tangent plane at a point on a non-flat surface. The function plots the values in matrix Z as heights above a grid in the x - y plane defined by X and Y.
