CYL3D(Zin,theta_min,theta_max,Rho,H,meshscale) plots the 3D profile Zin as a mesh plot on a cylindrical surface of radius Rho, with mesh size determined by meshscale, for equally spacedangles between theta_min and theta_max. H is the cylinder height. CYL3D(Zin,...,meshscale,plotspec) plots the 3D...

Auto Gaussian & Gabor Surface fit---2 functions to fit a 2D Gaussian or 2D Gabor to a surface. The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. This is done by evaluating the quality of fit (sum of squared error) for...
